sci-biology/foldingathome: misc ebuild impovements

- Added a systemd unit
- Removed usage of 'chown -R' on live filesystems
- Dropped the custom and vulnerable 'initfolding' helper script
- Improved the init script to use standard openrc-run behaviour via variables
- Dropped "unitinfo" extra command on /etc/init.d/foldingathome as it rarely works

Package-Manager: Portage-2.3.6, Repoman-2.3.1
