fsi-scan: make systemd wants relationship

systemd recommends a wants vs. requires relationship so this is a small
step in that direction for OpenBMC.

This also alleviates a common pain point in bringup where FSI is not
working properly or a FSI device is not present in the system. With a
requires relationship, the chassis poweron target fails. What a user
really wants is for the power on to still succeed.

Other firmware, which requires FSI, will detect issues during the host
boot and take proper actions.

Tested:
Injected fail into fsi-scan service and verified with this change that
chassis power on still succeeded.
