sched: Add USER_SCHED to feature removal list

Peter Zijlstra suggested that we remove USER_SCHED at . Removing USER_SCHED removes a
lot of code from the scheduler and simplifies the code.

We already have the ability to do user based classification which
is tightened using PAM in userspace.

+When: 2.6.34
+Why: USER_SCHED was implemented as a proof of concept for group scheduling.
+ The effect of USER_SCHED can already be achieved from userspace with
+ the help of libcgroup. The removal of USER_SCHED will also simplify
+ the scheduler code with the removal of one major ifdef. There are also
+ issues USER_SCHED has with USER_NS. A decision was taken not to fix
+ those and instead remove USER_SCHED. Also new group scheduling
+ features will not be implemented for USER_SCHED.
