android: i965: generate code for OA counter queries

Automake generation rules are replicated for android.
$* macro was expected to return "hsw" but instead gives "hsw.{h,c}"
so $(basename $*) is used as a workaround
to set the correct --chipset option for brw_oa.py script.

Build tested with nougat-x86
