vzctl 3.0.24 uname -a shows simple hostname instead of fqdn

When running vzctl 3.0.24 and running `uname -a` returns:

[root@backup /]# uname -a
Linux backup 2.6.18-194.3.1.el5.028stab069.6 #1 SMP Wed May 26 18:31:05 MSD 2010 i686 i686 i386 GNU/Linux
[root@backup /]#


It should return:

[root@backup /]# uname -a
Linux backup.domain.com 2.6.18-194.3.1.el5.028stab069.6 #1 SMP Wed May 26 18:31:05 MSD 2010 i686 i686 i386 GNU/Linux
[root@backup /]#

This behavior began with vzctl 3.0.24. After reverting to 3.0.23 behavior stopped. This is critical as we ran into a number of clients whose licensed software was affected because their software used `uname -a` to obtain their hostname instead of `hostname -a`.
