perf callchains: Fix unw_word_t pointer casts

unw_word_t is uint64_t even on 32-bit MIPS.  Cast it to uintptr_t before
the cast to void *p to get rid of the following errors:

  util/unwind-libunwind.c: In function 'access_mem':
  util/unwind-libunwind.c:464:4: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
  util/unwind-libunwind.c:475:2: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
  cc1: all warnings being treated as errors
  make[3]: *** [util/unwind-libunwind.o] Error 1
