lib: add new cgroup test API

Many of our LTP tests need Control Group in the configuration,
this patch makes cgroup unified mounting at setup phase to be
possible. The method is extracted from mem.h with the purpose
of extendible for further developing, and trying to compatible
the current two versions of cgroup,

It's hard to make all APIs be strictly consistent because there
are many differences between v1 and v2. But it capsulate the detail
of cgroup mounting in high-level functions, which will be easier
to use cgroup without considering too much technical thing.   

Btw, test get passed on RHEL7(x86_64), RHEL8(ppc64le), Fedora32(x86_64).
