sched/core: Fix build paravirt build on arm and arm64

Commit:

  004172bdad64432: ("sched/core: Remove unnecessary #include headers")

... in current -next removed the inclusion of asm/paravirt.h which
is used to get declarations of paravirt_steal_rq_enabled and
paravirt_steal_clock.

It is implicitly included on but not on arm and arm64 breaking the build
if paravirtualization is used.  Since things from that header are used
directly fix the build by putting the direct inclusion back.
