qemu_namespace: Move umount() call into #fdef __linux__

In a recent commit I've introduced an umount() call. But the
function where the call lives is compiled on all OSes, not just
Linux. But umount() is Linux specific. Other OSes have unmount
(FreeBSD), or maybe something else. But since namespaces are
Linux specific, we can wrap the call in #ifdef __linux__ and not
care about other OSes.
