comgt-ncm: add driver dependencies again

In the commit 623716dd43 ("comgt-ncm: Fix NCM protocol")
the dependencies to vendor NCM drivers were removed, because:

> comgt-ncm should not depend on the USB-serial-related kernel modules,
> as the cdc-wdm control device works without them. There is also no need
> to depend on kmod-huawei-cdc-ncm, since other manufacturers (like
> Ericsson and Samsung) which use other kernel modules should also be
> supported.

From a user-perspective this does not make sense, as installing comgt-ncm
(or luci-proto-ncm) should install all needed dependencies for using such
a device.

Furthermore depending on kmod-huawei-cdc-ncm does not mean that Ericsson
and Samsung devices can't be supported. By the way it seems that Ericsson
and Samsung devices never used NCM, but act as serial modems.

Thus this commit adds the dependencies again.
