ANDROID: Align x86-64 microdroid cgroup support with aarch64 microdroid

The x86-64 microdroid kernel currently supports a superset of cgroup
functionality when compared to the aarch64 kernel. This is not needed,
as microdroid only requires memory cgroup support. Therefore, remove
all cgroup support in the x86-64 kernel, except memory cgroup support.
