Call emit_interfaces signal for temporary interfaces

When an interface is removed, all the interfaces on that dbus
object are removed because the object class calls object_removed.
The code will be enhanced to handle the removal of interfaces with
openbmc/openbmc#1975 .

In the mean time, for interfaces that are temporary and removed
in the course of the code update flow, do not call emit_object_added
and call emit_interfaces_added and removed when they are created
and destroyed.

Resolves openbmc/openbmc#1917
