qemu-sockets: do not test path with access() before unlinking
Using access() is a time-of-check/time-of-use race condition. It is
okay to use them to provide better error messages, but that is pretty
much it.
This is not one such case; on the other hand, access() *will* skip
unlink() for a non-existent path, so ignore ENOENT return values from
the unlink() system call.
