pytools: Remove dependency to obmc.system
The system manager (obmc.system) is being deprecated and
the GPIOs has moved out of D-Bus (see openbmc/openbmc#3332).
The pytools still depend on the convertGpio function provided
by system manager, so copy that function into the tools that
use it to remove the dependency.
Tested: obmcutil power functions still work, and gpioutil
-l and -p work the same.
