description:
Fix warning in userdel -r.

If the 'rm -rf' works, then the home directory does not exist any more,
and rmdir() on it will return an error (ENOENT). Catch and ignore it.

Avoids:

# useradd -m foo
# userdel -r foo
userdel: Unable to remove all files in `/home/foo': No such file or directory
