Fix 12 Boring tests involving NULL-SHA ciphersuites

The Boring runner attempts to enable the NULL-SHA ciphersuite using the
cipherstring "DEFAULT:NULL-SHA". However in OpenSSL DEFAULT permanently
switches off NULL ciphersuites, so we fix this up to be "ALL:NULL-SHA"
instead. We can't change the runner so we have to change the shim to
detect this.
