Block files without trailing newlines
Add a pre-submit check to ensure that files have a newline character at
the end.
Please see https://android.googlesource.com/platform/tools/repohooks/
for documentation on how PREUPLOAD hooks work.
Test: created a change and watched the presubmit check reject it.
