This commit by intention reverts the

Do not provide and obsolete libpdb0 from libsamba-passdb0

change is the reported issue requires more investigation.

With the first suggested solution we have two issues:

a) a library name conflict as reported to Samba upstream at
https://bugzilla.samba.org/show_bug.cgi?id=10355

As libpdb depends heavily on other versioned shared Samba libraries
libpdb in the old version can't work alone. We'll end up in a
library missmatch.

b) libzypp (YaST/ zypper) pulls in libpdb0 _i586_ from the main openSUSE
13.2 repository for example

The actual package changes are:

- Package /var/lib/samba/private/sock with 0700 permissions; (bnc#946051).

- Package /var/lib/samba/msg with 0755 permissions; (bnc#945502).

- Require to install libfam0-gamin from samba-libs on post-12.1 and pre-13.15
systems; (bnc#945013).
