[PATCH] git-gui: Sort entries in optimized tclIndex

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 (7 lines below) was previously fixed in
v2.11.0-rc0~31^2^2~14 “git-gui: sort entries in tclIndex”.
