sys-apps/systemd: add symlinks to ease rootprefix migration

systemd holds the path to systemd and systemd-shutdown in memory.
The symlinks ensure that re-exec and reboot will work.
Also, the bootloader init option will not need to be updated immediately.

Package-Manager: Portage-2.3.5_p31, Repoman-2.3.2_p61
