Don't use SVN revision for Chromoting Android APK internal version.

An APK built from a later Chromium branch should have a higher version
number than one built from an earlier branch. This CL fixes the
Chromoting Android package's internal version to have that property.

The scheme implemented here matches official Chrome.apk.
