Set SNI ClientHello extension to localhost in tests

Browse Source 
The connection strings in the SSL client tests were using the host
set up from Cluster.pm which is a temporary pathname. When SNI is
enabled we pass the host to OpenSSL in order to set the server name
indication ClientHello extension via SSL_set_tlsext_host_name.

OpenSSL doesn't validate the hostname apart from checking the max
length, but LibreSSL checks for RFC 5890 conformance which results
in errors during testing as the pathname from Cluster.pm is not a
valid hostname.

Fix by setting the host explicitly to localhost, as that's closer
to the intent of the test.

Backpatch through 14 where SNI support came in.
