There are two versions of gem_exec_nop.c in benchmarks and tests
which causes the build system to have two build modules with
the same name.
This patch renames benchmarks/gem_exec_nop.c to
benchmarks/gem_exec_nop_benchmark.c using the existing
gem_userptr_benchmark.c as a naming convention.
v2: Also rename gem_mmap to gem_mmap_benchmark. Another file
which breaks android which was added after this patch was 1st
submitted.
