tests: Only run python SSL test if SSL support is configured

Only run python SSL test, which invokes ovsdb with a --remote=pssl,
if SSL support is configured.

Without this change the following error appears when running
the test-suite when OVS is configured with --disable-ssl.

+ovsdb-server: Private key specified but Open vSwitch was built without SSL support
./ovsdb-idl.at:1215: exit code was 1, expected 0

Fixes: d90ed7d ("python: Add SSL support to the python ovs client library")
