Ignore .nfs* files in distutils (#7719).
These files are created by some NFS clients a file is edited and removed
concurrently (see added link in doc for more info). If such a file is
removed between distutils calls listdir and copy, it will get confused.
Other special files are ignored in sdist (namely VCS directories), but
this has to be filtered out earlier.
