On all platforms, if the controlling tty isn't an actual tty, this is
flagged by setting is_a_tty to zero...  except on VMS, where this was
treated as an error.  Change this to behave like the other platforms.

The external BoringSSL tests had some failures as a result of
the extensions refactor. This was due to a deliberate relaxation
of the duplicate extensions checking code. We now only check
known extensions for duplicates. Unknown extensions are ignored.
This is allowed behaviour, so we suppress those BoringSSL tests.
