lib/Kconfig.debug: Restrict FRAME_POINTER for MIPS

commit 25c87eae upstream.

FAULT_INJECTION_STACKTRACE_FILTER selects FRAME_POINTER but
that symbol is not available for MIPS.

Fixes the following problem on a randconfig:
warning: (LOCKDEP && FAULT_INJECTION_STACKTRACE_FILTER && LATENCYTOP &&
 KMEMCHECK) selects FRAME_POINTER which has unmet direct dependencies
(DEBUG_KERNEL && (CRIS || M68K || FRV || UML || AVR32 || SUPERH || BLACKFIN ||
MN10300 || METAG) || ARCH_WANT_FRAME_POINTERS)
