Properly catch and report dbus timeout exception

openbmc/phosphor-state-manager#4 tracks an intermittent issue that is
being hit in hardware CI. The root cause is not yet known but this
commit will help in two ways:

- Ensure the error is where it's thought to be in the call to systemd
- Capture a dump (via InternalFailure) when the error occurs

Tested:
Verified good path still works. I can't find a way to force the error
path (or recreate the issue).
