From an original patch by Danish Prakash.
With commit ff22a78d7b ("pasta: Don't try to watch namespaces in
procfs with inotify, use timer instead"), if a filesystem-bound
target namespace is passed on the command line, we'll grab a handle
on its parent directory. That commit, however, didn't introduce a
matching AppArmor rule. Add it here.
To access a network namespace procfs entry, we also need a 'ptrace'
rule. See commit 594dce66d3 ("isolation: keep CAP_SYS_PTRACE when
required") for details as to when we need this -- essentially, it's
about operation with Buildah.
