[rsbac] MAC: request MODIFY_SYSTEM_DATA, target NETDEV

[Javier J. Martínez Cabezón]

Hmmm... I missunderstood one thing, target is NETDEV, so category
should go to NETDEV. It's better in my opinion to have categories in
all (as types in RC model) than granting a global access to all
objects with 0 security_level.
