Updated setup packages fix security vulnerabilities

Updated setup package fixes security issue

An issue has been identified in Mageia 4's setup package where the
/etc/shadow and /etc/gshadow files containing password hashes were created
with incorrect permissions, making them world-readable (mga#14516).

This update fixes this issue by enforcing that those files are owned by
the root user and shadow group, and are only readable by those two entities.

Note that this issue only affected new Mageia 4 installations. Systems that
were updated from previous Mageia versions were not affected.

This update was already issued as MGASA-2015-0116, but the latter was withdrawn
as it generated .rpmnew files for critical configuration files, and rpmdrake
might propose the user to use those basically empty files, thus leading to
loss of passwords or partition table. This new update ensures that such .rpmnew
files are not kept after the update.
