[md68k] udeb: Use only the common module list for nic-shared-modules (fixes FTBFS)

Delete all the additional lines:
- 7990, 82596 and 8390p are now included in nic-modules, resulting in the
  "some modules are in more than one package" error
- 8390 and libphy are already listed in the common module list
- There's no particular reason to think m68k needs the dummy driver
