cgroups-mount,docker-ce,lxc: rework kernel feature dependency

Fix that KERNEL_CGROUPS is enabled (selected) automatically along with
cgroups-mount

Replace "if PACKAGE_docker-ce" with a menu to avoid circular denpendency
issue involving PACKAGE_docker-ce, PACKAGE_cgroups-mount and
KERNEL_CGRUOPS

docker-ce, lxc: replace KERNEL_LXC_MISC with more specific options
