Add a local .gitignore file for tools/python.

As at least on some systems (e.g. OpenSUSE Leap 15.5) the build will
produce a tools/python/xen.egg-info directory, add it to the new
.gitignore file, too.

Use "/dir/" as pattern for ignoring a directory and its contents, as
the "/dir/*" pattern won't ignore the directory itself (git just
doesn't complain when seeing a directory without any not ignored file
in it).
