Include sys/glibc-syscalls.h instead of inexistent sys/io.h on Android

This won't make raw I/O work magically but at least it would provide iopl()
if some driver requires it and there is no better alternative currently.

Corresponding to flashrom svn r1932.

* On Android we don't have the header file and no way for I/O port access at all. However, sys/glibc-syscalls.h
