kernel: kmod-wwan: Add package

This adds the kmod-wwan package. This provides the generic wwan driver
core which is needed for some existing packages.

Currently the drivers/net/wwan/wwan.ko driver is compiled into the
kernel when one of the wwan module is activated, better build it as a
kernel module.
