Kernel module packages: Add DVB support

Adds DVB drivers intended to be used with tvheadend package and easily available Astrometa USB DVB+analog tuners. More adapters can be added in the future.
This allows users to record and stream TV programs from DVB networks to tvheadend clients.

Changes:
- Add packages for these kernel modules:
  - Multimedia support (installs mc.ko)
  - DVB core (installs dvb-core.ko)
  - DVB USB v2 (installs dvb-usb-v2.ko)
  - Drivers for chips used in Astrometa DVB:
    - Rafael Micro R820T
    - Realtek RTL28xxU, RTL2830, RTL2832
    - Panasonic MN88472 (no firmware)
    - Panasonic MN88473 (no firmware)
    - Sony CXD2841ER
- Added new kernel config lines for v5.15, v6.1, v6.6
- USB audio needed a dependecy on kmod-multimedia, when kmod-multimedia is also selected.
