make-automaps: Replace 'nfsd41' by 'nfs40'

We used to tag hosts, which are trusted to serve nfs with version >4.0
with the tag 'nfsd41'. Now we want to switch that to a alternative tag
for hosts, which are not trusted to server nfs>4.0. The new tag is
'nfs40' and the meaning is the opposite.

Change code to honor the 'nfs40' tag instead of the 'nfsd41' tag.
