test//bio_dgram_test.c: Skip test when BIO_bind() fails

This test isn't supposed to test BIO_bind() itself, so we can be a bit
sloppy and assume that it fails because the attempted binding is not
supported on the platform where this is run.  For example, BIO_bind()
fails when it's given an IPv6 address and the platform where this is
run doesn't support that address family.

In a case like this, it's sensible enough to simply skip the test when
BIO_bind() fails.
