sched: Export hidden tracepoints to modules
The tracepoints sched_entry, sched_exit and sched_set_need_resched
are not exported to tracefs as trace events, this allows only kernel
code to access them. Helper modules like [1] can be used to still have
the tracepoints available to ftrace for debugging purposes, but they do
rely on the tracepoints being exported.
Export the 3 not exported tracepoints.
Note that sched_set_state is already exported as the macro is called
from modules.
