[PATCH 2/3] git-gui: sort entries in optimized tclIndex

[Jonathan Nieder <jrnieder@gmail.com>]

From: Anders Kaseorg <andersk@mit.edu>

auto_mkindex expands wildcards in directory order, which depends on
the underlying filesystem.  To improve build reproducibility, sort the
list of *.tcl files in the Makefile.

The unoptimized loading case was previously fixed in gitgui-0.21.0~14
(git-gui: sort entries in tclIndex, 2015-01-26).
