Controling the test USE flag alone without the test FEATURE is useless, since it wont run the
src_test phase. And being able to disable the test USE flag with FEATURES=test will result in
missing deps or build-system args. Can you tell me any reason, why you want to expose and control
the test USE flag independently of FEATURES=test?
