ANDROID: fix up crc issue for cpuset_cpus_allowed()

In commit 68832507 ("cgroup/cpuset: Prevent UAF in
proc_cpuset_show()"), a new .h file is added to kernel/cgroup/cpuset.c
which ends up changing the CRC for cpuset_cpus_allowed().  Fix this up
by only including it in the real build, not when generating the looney
crc values.

Fixes: 68832507 ("cgroup/cpuset: Prevent UAF in proc_cpuset_show()")
