[PATCH] gitk - work around stderr redirection on Cygwin

[Mark Levedahl <mlevedahl@gmail.com>]

Cygwin is *still* shipping with antiquated Tcl 8.4.1, and will continue
to do so for the indefinite future. This version does not understand
the "2>@1" redirection syntax, so such redirection of stderr must be
done using sh.
