Updated shadow-utils package

An updated shadow-utils package that fixes locking in useradd is now
available.

The shadow-utils package includes the necessary programs for converting
UNIX password files to the shadow password format, as well as programs for
managing user and group accounts. The pwconv command converts passwords to
the shadow password format. The pwunconv command unconverts shadow
passwords and generates an npasswd file (a standard UNIX password file).
The pwck command checks the integrity of password and shadow files. The
lastlog command prints out the last login times for all users. The useradd,
userdel, and usermod commands are used for managing user accounts. The
groupadd, groupdel, and groupmod commands are used for managing group accounts.

The useradd command did not properly unlock the user and group database
files on exit. This has been fixed.

All users of shadow-utils should upgrade to this updated package, which
resolves the issue.
