[bug#49329] [PATCH v2 4/5] gnu: renpy: Correct inputs.

[Leo Prikler <leo.prikler@student.tugraz.at>]

* gnu/packages/game-development.scm (renpy)[#:modules]: Add SRFI-1.
[#:imported-modules]: Likewise.
[#:phases]<fix-commands>: Search for ‘python2’ and ‘xdg-open’ in inputs.
<start-xserver>: Search for ‘xorg-server’ in native-inputs.
<install>: Search for ‘python2’ in inputs.
<wrap>: Search for python dependencies in inputs.
[inputs]: Add python2, drop python2-pygame (already propagated by
python2-renpy). Move xorg-server from here…
[native-inputs]: … to here.
[propagated-inputs]: Empty.
