Make systemd support in seatd explicit

[Micket]

(created using eb --new-pr)

Hitting some issues with this. If one build with osdep to systemd-devel, then pkgconfig files need to also be able to find the OS level libsystemd.pc, which we block. So lets just disable it explicitly, since it's not that useful for HPC environments.
