Fix compile issue caused by AOSP rebase

latest AOSP add 'bionic/libc/include' to exported_include_dirs.
It will make efiwrapper use external c header files (e.g. stddef.h
stdio.h, stdlib.h, inttypes.h) under 'bionic/libc/include'.
So some compile issue happen. The fix is to make efiwrapper keep
using original c heard files.
