perf symbols: Use symbol type instead of map->type

map->type is going away, we can derive it from map->prot, so use
the same logic as in the kernel's arch/arm/kernel/module.c file:

  ELF32_ST_TYPE(sym->st_info) == STT_FUNC && !(sym->st_value & 1))

This was introduced in b2f8fb237e9c ("perf symbols: Fix annotation of
thumb code"), that fix is maintained with this change.
