Revert "libdrm: intel/Android.mk: Filter libdrm_intel library requirements on x86/x86_64"

This reverts commit ed07718ae7bab596297abf210bb0c37c6dba58ed.

The commit added a guard since libpciaccess may be missing on some
setups. As of last commit there are no traces of the project, from
Android POV.

Hence, we can revert this workaround - which caused similar breakage to
the one it's trying to fix. This time in Mesa.
