De-duplicate SHA1-independent test in ssl-opt.sh

The splitting of this test into two versions depending on whether SHA-1 was
allowed by the server was a mistake in
5d2511c4d48eb197697466d1bd6b776cf09b0e7c - the test has nothing to do with
SHA-1 in the first place, as the server doesn't request a certificate from
the client so it doesn't matter if the server accepts SHA-1 or not.
