sd-daemon: fix sd_is_mq for non-mq fds

mq_getattr returns -1/EBADF for file descriptors which are not mq.
But we should return 0 in this case.

We first check that fd is a valid fd, so we can assume that if
mq_getattr returns EBADF, it is simply a non-mq fd. There is a slight
race, but there doesn't seem to be a nice way to fix it.
