v2v: tell v2v the real root device to mkinitrd

Browse Source 
Complementary fix of commit 2d25872df3.
On SLES 11 SP4 with kdump enabled mkinitrd calls mkdumprd which calls
mkinitrd, but mkdumprd doesn't have any clue of the root device.

Call mkinitrd with rootdev environment variable to tell them all
what device to use as root.
