SSLSocketTest: add error message test for fallback_scsv

The upgrade to OpenSSL 1.0.1j caused a regression for the error message
produced by inappropriate fallback protection mechanism. Add a test to
make sure this doesn't happen again.

(cherry picked from commit cce4d86d447d0e86f94035dd0285726c4025fae6)
