benckmarks/Android.mk: Fix building benchmarks for Android

The commit "benchmarks: Do not install to system-wide bin/" changed
the benchmark file list from bin_PROGRAMS to benchmarks_PROGRAMS.
However Android.mk was not updated, resulting in IGT failing to
build for Android.
This commit adds that change. It also adds LOCAL_MODULE_PATH to
specify where the built benchmarks should be put.

v2: I discovered that the existing definitions of LOCAL_MODULE_PATH
were creating what should have been an invalid path. Not sure how it
was ever working previously, but fixed now.
