Catch SdBusError when calling the mapper

In certain cases, the mapper may return a not found error when polling
for BMC endpoints.  While this is an error, it should not crash
phosphor-software-manager.

Tested By: Booted the system without a bmc interface present, and
verified that software manager doesn't crash
