services/ssh: Don't audit accesses from ssh_t to /dev/random

Browse Source 
OpenSSL 1.1 always opens both /dev/urandom and /dev/random, which
generates spurious denial messages for ssh_t, ssh_keygen_t and probably
various other domains too.

The code only uses /dev/random as a fallback and can cope with an open()
failure just fine, so I'm dontauditing the access. However, I don't have
strong feelings about this -- if someone would prefer to allow these
accesses instead, I'd be okay with that too.
