minijail: Don't unmount proc if not mounted
When switching in to a new mount and a new pid namespace, as well as
doing pivot_root, proc won't be mounted so leave it alone and let the
new init process handle mounting it. Rename the readonly flag to
remount_proc_ro which better reflects its meaning.
This will aid in starting complete, containerized systems with minijail.
