unshare: fix busyloop and reduce racing probability
Replace busy-loop with waiting on pipe from parent.
Note: reduces racing probability, but still there are window where
it is possible (if parent unshare process will be [externally] killed
between successful read(fds[0]) and mount() calls).
[kzak@redhat.com: - use all-io.h to avoid loops around write() and read(),
- use less generic 0x06 byte to sync parent and child]
