[PATCH 5/5 v2] contrib/diffall: fix cleanup trap on Windows

[Tim Henigan <tim.henigan@gmail.com>]

Prior to this commit, the cleanup trap that removes the tmp dir
created by the script would fail on Windows. The error was silently
ignored by the script.

On Windows, a directory cannot be removed while it is the working
directory of the process (thanks to Johannes Sixt on the Git list
for this info [1]).

This commit eliminates the 'cd' into the tmp directory that caused
the error.
