git-gui: always use themed widgets from ttk

git-gui optionally uses themed ui elements from ttk, but the full set of
ttk ui elements is always available with Tk 8.6.  Keeping code making
ttk use optional increases maintenance burden for no benefit.  Let's use
ttk always, allowing removal of alternate code paths in subsequent
patches.
