GEODE-151: Convert to use Gradle Git plugin

The build was using the executable git command to populate version
information, which created big blocks of Gradle code and could be
unstable. All Git executable commands have been changed to use the
Gradle Git plugin. If directory is not a valid Git workspace, then
it will log a warning and use default values to populate version
information.

Tested with and without Git workspace
