xdgmenumaker: fix deps, enable python3, use build_style, install manpage
- Removed python3 (python3 libs will install it), removed pygtk (used only with python2), changed python-gobject to python3-gobject to work with python3 and added python3-Pillow (optional dependency).

- Changed the shebang to #!/usr/bin/python3 - it is changed to python2 by the pre-pkg hook otherwise.

- The manpage is generated on build time by txt2tags which is not maintained, written in python2 and absent from the repo. I compilled the manpage locally.
