[glib] build: Drop data-to-c.pl in favour of data-to-c.py

[Philip Withnall <pwithnall src gnome org>]

commit 1897e66dce271027512497bd9db70f155d9bf9d7
Author: Philip Withnall <withnall endlessm com>

    build: Drop data-to-c.pl in favour of data-to-c.py
    
    The Python version was added for the Meson build, but we might as well
    use it from autotools too, since it does exactly the same thing as the
    Perl version (modulo not including a trailing linebreak, but that
    doesn’t matter).
    
    Works fine with Python 2.7 or Python 3.
