PATCH: stop [[ -N file ]] test failing under NFS

[Peter Stephenson <pws@xxxxxxx>]

This is to prevent the perennial error in the test suite when using [[
-N file ]] under NFS because it doesn't store modification time and
access time separately.  The "-fstype nfs" test of find is widely enough
supported that we can use that (I've written it so we're no worse off if
it doesn't work).

Probably something similar would work on HFS+, but as is widely known we
don't have a Mac OS X expert.
