sched/wait: Include <linux/wait.h> in <linux/swait.h>
kbuild bot reported against an intermediate RT patch that the build
fails with:
> In file included from include/linux/completion.h:12:0,
> from include/linux/rcupdate_wait.h:10,
> from kernel/rcu/srcutiny.c:27:
> kernel/rcu/srcutiny.c: In function 'srcu_drive_gp':

That error vanishes a few patches later (in the RT queue) because wait.h
is then pulled in by other means. It does not seem to surface on !RT.
I think that swait should include a header file for a function/macro
(___wait_is_interruptible()) it is using.
