Carlo Marcelo Arenas Belón bffcb4d9d6 git-cvsserver: protect against NULL in crypt(3) ...

Some versions of crypt(3) will return NULL when passed an unsupported
hash type (ex: OpenBSD with DES), so check for undef instead of using
it directly.

Also use this to probe the system and select a better hash function in
the tests, so it can pass successfully.
