I don't know why struct k_itimer was ever declared in sched.h; perhaps at
one time it was referenced by something else there.  There is no need for
it now.  This patch moves the struct where it belongs, in
linux/posix-timers.h.  It has zero effect on anything except keeping the
source easier to read.
