François Cami 27e9988fe2 ipatests: xfail TestIpaClientAutomountFileRestore's final test
Due to a change in authselect, rolling back the installation
does not produce the same nsswitch.conf as on a clean install.
Mark the test xfail until ipa-client-install is enhanced to
use authselect profile backup/restore.

"""This module provides tests for NFS-related features like
krb5 NFS and automount locations.
Wishlist
* add automount direct and indirect maps
* add automount /home for the "seattle" location only
* validate it is not available in another location
* krb5 /home for IdM users in test_automount
* store nfs configuration in a single place
