systemd: install in multi-user.target

Installing in basic.target adds an ordering dependency on every single
unit to entity-manager and fru device.  Avoid all these unnecessary
implicit dependencies by installing in multi-user instead.

Testing consisted of booting a rainier bmc to multi-user with any
issues.  It should be noted that the rainier target has very few
applications with dependencies on entity-manager and does not presently
use fru-device at all.
