libprocessgroup: Fix cgroup directory ownership setup
When cgroup directory is created its user and ownership gets set, however
because previous code was storing getpwnam() return value the second
invocation would effectively override the previous ones result. Fix this
by copying necessary results. Also change getpwnam() to getgrnam() when
group name is converted into gid. getpwnam() works because of the way
Android uses these ids, however more generally this is incorrect and
getgrnam() should be used instead.
