The current power direction of an USB-C port also influences the
power_supply's online status, so a power role change should also update
the power_supply.

Fixes an issue on some systems where plugging in a normal USB device in
for the first time after a reboot will cause upower to erroneously
consider the system to be connected to AC power.
