xencommons: Attempt to load blktap2 driver
Older kernels, such as those found in Debian Squeeze:
* Have bugs in handling of AIO into foreign pages
* Have blktap modules, which will cause qemu not to use AIO, but
which are not loaded on boot.
Attempt to load blktap in xencommons, to make sure modern qemu's which
use AIO will work properly on those kernels.

Prefer to load blktap2 if it exists. This is the name of the driver in
classic-Xen ports, while in mainline kernels the driver is called just
blktap.
