If lib.optional is given a false value it will return an empty list. Thusly the set-environment script can have ``` export GTK_USE_PORTAL= ``` This can rub certain bugs the wrong way #65679 so lets make sure this isn't set in the environment at all.

For example, you'd need to set this for non-flatpak Firefox to use native filechoosers.

Defaults to <literal>false</literal> to respect its opt-in nature.
