difftastic: migrate to lib.cli.toCommandLineShellGNU

Browse Source 
Migrates from the deprecated toCommandLineShell to toCommandLineShellGNU.

This changes the output format to use GNU-style concatenated options
(--color=always) with shell escaping for git config values. Both formats
were verified to work correctly with difftastic.
