Subject: [PATCH] Add gentoo-env-to-systemd

This script transforms Gentoo's /etc/profile.env to a systemd user
unit environment configuration file placed in /usr/lib/environment.d
named gentoo-env.conf.

The script is meant to be invoked by a, not yet existing, env-update
hook that is invoked after /etc/profile.env was (re-)generated.
