Change PRESUBMIT to try more cls on android
Change PRESUBMIT to try more cls on android

- android doesn't currently build anything in chrome/
  so we're changing try job logic to send builds to android
  unless the CL was exclusively in chrome/

Previously we would have built on roughly 20% of cls with 'git try'
After this change we will build on roughly 60% of cls (based on last 10k
commits)
