packagegroups: Remove obmc-mgr-system

The system manager (obmc-mgr-system) which provided GPIO
functionality is being deprecated and it's not in use anymore:
* GPIOs have moved out of D-Bus (see openbmc/openbmc#3332).
* Tools depending on its GPIO functions have been updated to
call local functions instead.
* The systemd service files have been updated to not depend
on system manager.
