The old cipherlist test in ssltest.c only tests the internal order of
the cipher table, which is pretty useless.

Replace this test with a test that catches inadvertent changes to the
default cipherlist.

Fix run_tests.pl to correctly filter tests that have "list" in their name.

(Also includes a small drive-by fix in .gitignore.)
