[PATCH] remove two obsolete net drivers

  
  The options FMV18X and SK_G16 do depend on the non-available
  CONFIG_OBSOLETE even in kernel 2.4 - IOW, the last time it was able to
  select them was in kernel 2.2 (or even before).
  
  Since it seems noone misses these drivers, this patch removes them.
