kmemtrace, rcu: don't include unnecessary headers, allow kmemtrace w/ tracepoints

Impact: cleanup

linux/percpu.h includes linux/slab.h, which generates circular inclusion
dependencies when trying to switch kmemtrace to use tracepoints instead
of markers.

This patch allows tracing within slab headers' inline functions.
