[PATCH] move _STK_LIM to <linux_resource.h>

I don't see any connection between the stack limit and scheduling.  So I
think _STK_LIMIT is better defined in <linux/resource.h> than in
<linux/sched.h>.

The only place STK_LIM is used is in <asm/resource.h>, which only gets
included by <linux/resource.h>, so no change in #includes is necessary.
