While the chat script is able to establish the PPP connection,
it's closed instantly by the modem: LCP terminated by peer.

To send this AT command to the modem the "runcommand.gcom" script
dependency is moved from comgt-ncm to comgt.
As the comgt-ncm package depends on comgt already, this change
is a NOOP from that point of view.
But from the modem's point it is a low hanging fruit as the modem
is usable with installing comgt and kmod-usb-ncm packages.
