treewide: change EM's ObjectManager path

EntityManager moves its ObjectManager in commit [1], this patch is to
change accordingly. Please see [1] for why we made that change.

[1] https://gerrit.openbmc.org/c/openbmc/entity-manager/+/57279

Tested: code compiles. I don't have a system with this repo enabled.
But code inspection can show that only ObjectManager path changed.
