Bug#827095: base-files and libc-bin install different /etc/nsswitch.conf files

[Sven Joachim <svenjoac@gmx.de>]

Package: base-files,libc-bin

Both base-files and libc-bin install the /etc/nsswitch.conf file.
Although it has been agreed in #673271 that libc-bin should take over
responsibility for it, base-files still installs and updates it.
Moreover, in response for #699090 base-files has updated its copy, and
now it differs from libc-bin's version:

The net effect is apparently that the content of /etc/nsswitch.conf in
fresh installations depends on whether libc-bin or base-files is
configured first, which is bad.  Could you please work out who should be
responsible for that file?
