[PATCH bpf-next] selftests/bpf: fix compilation error in progs/profiler.inc.h

[Song Liu]

Fix the following error when compiling selftests/bpf

progs/profiler.inc.h:246:5: error: redefinition of 'pids_cgrp_id' as different 
kind of symbol

pids_cgrp_id is used in cgroup code, and included in vmlinux.h. Fix the
error by renaming pids_cgrp_id as pids_cgroup_id.

Fixes: 03d4d13fab3f ("selftests/bpf: Add profiler test")
