sched: x86: allow single-depth wchan output

sched.o gets smaller and faster if we compile it with -fomit-frame-pointers,
so make this a config option. The cost is the loss of multi-depth wchan
lookups - but SysRq-T is a sufficient replacement for them anyway, so their
utility is much lower these days.

the size difference is significant:

   text    data     bss     dec     hex filename
  34005    3462      24   37491    9273 sched.o.before
  33470    3462      24   36956    905c sched.o.after
