[PATCH 2/3] apparmor: Expand scope of @{run}/user access, allow writing PID files too

With Podman's custom networks, pasta will typically need to open the
target network namespace at /run/user/<UID>/containers/networks:
grant access to anything under /run/user/<UID> instead of limiting it
to some subpath.

Note that in this case, Podman will need pasta to write out a PID
file, so we need write access, for similar locations, too.
