[Intel-gfx] [PATCH i-g-t 2/3] configure.ac: Make glib dependency optional to preserve Android build

[Paul Kocialkowski]

This adds ifdef wrappers, with matching autoconf macros, to make the
dependency on glib (used for parsing configuration) optional.

This allows preserving the ability to build IGT on Android, where glib
support is lacking.
