Bug#596772: OpenVZ ioprio must be configured via kernel config for 2.6.32

I have stated it in the bug at openvz.org already [1]: this is not a
OpenVZ bug, but a packaging issue:

Apparently this feature requires CONFIG_BLK_CGROUP, which is not
available with stock 2.6.32 (only available from 2.6.33 according to

However, the OpenVZ patch contains this config, but it does not get
enabled via the Debian build config.

This patch should fix it. I have done a rebuild using it, and do not get
an error for "vzctl set $VZ --ioprio" anymore.
