vzctl.spec: drop the Conflicts: vzkernel
The change this patch is reverting was introduced to fix bug #3094.
Unfortunately, it breaks the update for RHEL5-based OpenVZ kernels,
which is the subject of bug #3219.
The only solution I found is to list all the old RHEL6-based kernel
explicitly. It would be good enough, but looks ugly.
As the newest RHEL6-based kernel conflicting with this vzctl is at least
2 years old, let's just drop the "Conflicts: vzkernel" line. This makes
vzctl to fail on older kernels, but well, two-years old kernels is full
of securuty holes and bugs, please, just upgrade it already.
