bus-socket: Skip cap check instead of -ENOSYS

Returning -ENOSYS meant that any permission check would fail if we
didn't have capabilities, which lead us to fail before seeing that
server/client were the same PID, which is special-cased to be okay.

Instead set -1, so that we just skip capability tests.
