libpq: Remove a gettext marker

This one error message is just a workaround for a missing OpenSSL
error string.  But OpenSSL does not have gettext support, so we don't
need to provide it in our workaround either.  That way, the
user-facing behavior is consistent whether the user has a fixed
OpenSSL or not.
