selinux: Allow pasta to remount procfs

Browse source 
Partially equivalent to commit abf5ef6c22 ("apparmor: Allow pasta
to remount /proc, access entries under its own copy"): we should
allow pasta to remount /proc. It still works otherwise, but further
UID remapping in nested user namespaces (e.g. pasta in pasta) won't.
