Remove redundant PRESUBMIT.py files.

* tools_webrtc/PRESUBMIT.py is only checking the licence which is already done here:
38f35db4d4:PRESUBMIT.py;l=913;bpv=1;bpt=0;drc=4fc9bd9f69a0d88889d86d0cc9f8e27406e8a342

* sdk/android/PRESUBMIT.py was added before 'git cl format' was required from the root PRESUBMIT.py:
https://codereview.webrtc.org/2377113003
