Split out TRACE() from litmus.h and cleanup some includes

The TRACE() functionality doesn't need all of litmus.h. Currently,
it's impossible to use TRACE() in sched.h due to a circular
dependency. This patch moves TRACE() and friends to
litmus/sched_debug.h, which can be included in sched.h.

While at it, also fix some minor include ugliness that was revealed by
this change.
