utils/genrandconfig: more igh-ethercat tweaks

utils/genrandconfig already had some logic to disable building
igh-ethercat drivers since they are highly kernel version
specific. Commit
eec3a1108a65ab8de4a313a7f34205c5d5ad8f2b ("package/igh-ethercat: add
configuration options") recently added a number of additional config
options to build more igh-ethercat drivers, which causes a number of
autobuilder failures. This commit therefore updates genrandconfig to
also not build those new drivers.

Fixes:
