sched/rt: Fix Sparse warnings due to undefined rt.c declarations

Browse Source 
There are several symbols defined in kernel/sched/sched.h but get wrapped
in CONFIG_CGROUP_SCHED, even though dummy versions get built in rt.c and
therefore trigger Sparse warnings:

  kernel/sched/rt.c:309:6: warning: symbol 'unregister_rt_sched_group' was not declared. Should it be static?
  kernel/sched/rt.c:311:6: warning: symbol 'free_rt_sched_group' was not declared. Should it be static?
  kernel/sched/rt.c:313:5: warning: symbol 'alloc_rt_sched_group' was not declared. Should it be static?

Fix this by moving them outside the CONFIG_CGROUP_SCHED block.

[ mingo: Refreshed to the latest scheduler tree, tweaked changelog. ]
