[DD] Keep the network drivers infs 8.3 like on MS Windows (#7007)

Windows has all its network drivers inf files in 8.3.

This is an addendum to 0.4.15-dev-52-g 019f21ee1d
which moved us further away from our target.

The commit on its own was a good idea actually to get the inf into the drivers directory
and therefore simplifies adding and excluding drivers more locally (e.g. excluding works by
adding a single hashtag within the specific drivers CMakeLists.txt now).

But that cool feature doesn't require us to move away from our target.

For the record:
The historic netrtpnt.inf and netisa.inf (both 8.3) have been merged to
netne2000.inf (not 8.3) by 0.4.15-dev-2763-g 6924b8ff39
Unification of that was cool too,
but again: 8.3 is superior. Therefore netne.inf for that.

Worst of all: Since the .inf files did contain their filename within a comment also, that means
the historic renaming by the mentioned commit invalidated that comment.
netamd.inf fixed by restoring the ancient filename before 0.4.15-dev-52-g 019f21ee1d
netrtl.inf fixed by restoring the ancient filename before 0.4.15-dev-52-g 019f21ee1d
netne.inf I fixed the comment manually.
