gitk: make sha1but a ttk::button

gitk's 'Commit ID' button uses a classic widget, not a themed one,
leading to inconsistent style. Commit 51a7e8b654 (d93f1713b0 ("gitk: Use
themed tk widgets", 2009-04-17) that added themed widgets did not touch
this particular widget, but does not say why. Regardless, let's use a
themed button to be consistent with the rest of the interface.
