[PATCH i-g-t v13 01/11] include/android: Add stub for procps and glib

[Jeevaka Prabu Badrappan]

From: Sapna Singh <sapna1.singh at intel.com>

As procps, glib are not available in Android, not able to build igt
for Android.

Provided stub implementations so igt can be compiled for both Android
and linux from same code base. In case of linux systems, system
libraries will be used whereas for Android stubs will be used with
reduced test coverage.
