[PATCH v2 2/3] gitk: _search_exe is no longer needed

[Mark Levedahl <mlevedahl@gmail.com>]

The _search_exe variable allows specifying the suffix used for executables,
typically {} on unix, .exe on Windows. But, the override code is now
used only on Windows, so _search_exe is no longer needed. Eliminate it.
