To my surprise, it turns out that on OpenVMS, opening './' (which
is translated to '[]') for writing actually creates a file, '[].'.
On OpenVMS, this is a perfectly valid file with no name or extension,
just the delimiter between the two.

Because of the mess the exception would generate in the test recipe,
it gets refactored again, to clearly separate each test inside it,
and use skips to avoid some of them (that makes it clear that they are
skipped and why, when running the recipe).

The actual functionality of generating signatures through the `EVP_PKEY`
API is completely untested.
Current tests under the `EVP_PKEY` API
(`test/recipes/30-test_evp_data/evppkey.txt`) only cover `Verify` and
`Decrypt`, while encryption and signature generation are tested with
ad-hoc clients (`test/sm2crypttest.c`, `test/sm2signtest.c`) that do not
call the `EVP_PKEY` interface at all but soon-to-be private functions
that bypass it (cf. PR#5895 ).

It is my opinion that an ideal solution for the future would consist on
enhancing the `test/evp_pkey` facility and syntax to allow tests to take
control of the PRNG to inject known nonces and validate the results of
`EVP_PKEY` implementations against deterministic known answer tests, but
it is probably too late to work on this feature in time for next release.

Given that commit b5a85f70d8 highlights some critical bugs in the hook
between the `EVP_PKEY` interface and SM2 signature generation and that
these defects escaped testing and code review, I think that at least for
now it is beneficial to at least add the kind of "bogus" testing
provided by this patch:
this is a "fake" test as it does only verify that the SM2 `EVP_PKEY`
interface is capable of creating a signature without failing, but it
does not say anything about the generated signature being valid, nor
does it test the functional correctness of the cryptosystem.

Currently, critical bugs prevent using SM2 signatures through the
`EVP_PKEY` interface: any application that managed to satisfy the
requirement of forcing SM3 as the message digest – even if this is
currently not possible transparently through the `EVP_PKEY` interface
and requires manually forcing the MD selection – would crash with a
segmentation fault upon calling the `SM2_sign()` function.

This is easily verified using the OpenSSL CLI to execute this critical
code path under the right conditions:
`openssl dgst -sm3 -hex -sign sm2.eckey /path/to/file/to/sign`

The issue is caused by a double free at the end of `SM2_sign()` in
`crypto/sm2/sm2_sign.c` in case of successful signature generation.
In addition, even if the double free was not causing segfaults,
the function returns the wrong return value in case of success (it
would return 0 rather than 1).

This patch fixes both problems.

In 1.0.2 and below we always send the same client_version in a reneg
ClientHello that we sent the first time around, regardless of what
version eventually gets negotiated. According to a comment in
statem_clnt.c this is a workaround for some buggy servers that choked if
we changed the version used in the RSA encrypted premaster secret.

In 1.1.0+ this behaviour no longer occurs. This restores the original
behaviour.
