sys-apps/xdg-desktop-portal: provide default portal config

Install a default to avoid breakage: >=1.18.0 assumes that DEs/WMs
will install their own, but we want some fallback in case they don't
(so will probably keep this forever). DEs need time to catch up even
if they will eventually provide one anyway. See bug #915356.

TODO: Add some docs on wiki for users to add their own preference
for minimalist WMs etc.

Thanks to abby from Void for pointing me to https://github.com/void-linux/void-packages/commit/b4c404aac0af3ced08671a8840cd261198689cef
and psykose as well.
