systemd-units: move state units to own inc

The openbmc project is moving away from obmc-phosphor-systemd and its
SYSTEMD_LINK macros in favor of more explicit package based
installation. This commit gets phosphor-state-manager going in the right
direction so that future targets and services can build on the new way
to do things.

The chassis/host action and synchronization targets still need some
additional thought and effort.

Tested:
Booted up image in QEMU and spot checked a few services ensuring they
were still in the expected locations.

(From meta-phosphor rev: 5059a445b94e70efa7d6c90c1b5e7aa755dfe1d7)
