perf top: Add cgroup support for perf top (-G)
Added callback option (-G) to support cgroups for 'perf top'.
Added condition to make sure -cgroup and --all-cgroups aren't both enabled.
Example:
$perf top -e cycles -G system.slice/docker-6b95a5eb649c0d671eba3835f0d93973d05a088f3ae8602246bde37affb1ba3e.scope -a --stdio
