base-files: add nsswitch-resolved.conf and remove nsswitch patch

Due to changes to nsswitch.conf file on commit 0cb122f17cf2
("base-files: add gshadow entry in nsswitch.conf"), the current patch
does not apply anymore due to patch fuzz.

This fuzz wasn't detected before because this is a conditional patch,
and will be hard to detect if nsswitch.conf changes again.

Instead, add a new version of nsswitch.conf, called
nsswitch-resolved.conf, which will later be renamed accordingly based on
the DISTRO_FEATURES variable. This file contains the necessary changes
which were applied by the patch before.
