meta-fii: meta-mori: Enable dynamic-sensors feature

Enable dynamic sensors for phosphor-ipmi-host. This allows us to use the
entity manager decorators, e.g. for the FRU device names.

This change is necessary as of this commit:
https://github.com/openbmc/phosphor-host-ipmid/commit/23a722ca7c6ca2ac93a8ecbe44550e9429e1a8f1

Tested:
Ran "ipmitool fru" on the BMC and confirmed that the FRU Device
Description fields are populated (not UNKNOWN).
