Lennart Poettering f6793bbcf0 killall: gracefully handle processes inserted into containers via nsenter -a
"nsenter -a" doesn't migrate the specified process into the target
cgroup (it really should). Thus the cgroup will remain in a cgroup
that is (due to cgroup ns) outside our visibility. The kernel will
report the cgroup path of such cgroups as starting with "/../". Detect
that and print a reasonably error message instead of trying to resolve
that.

nsresourced: don't specify REMOVE_PHYSICAL, remove redundant safety check
Even without REMOVE_PHYSICAL, rm_rf() permits cgroupfs, hence
just delegate the safety check to that.
