[PATCH OSSTEST v2 10/15] distros: support booting Debian PV (d-i installed) guests with pvgrub.

[Ian Campbell <ian.campbell@citrix.com>]

This requires the use of the pv-grub-menu package which is in Jessie onwards.
(it is in wheezy-backports which is the subject of a subsequent flight).

The bootloader to use is specified via a runvar {Guest}_bootloader.

Adjust make-distros-flight to use pvgrub for some subset of i386 and amd64
guests to get coverage.
