[Libguestfs] [PATCH] v2v: Don't hang when rebuilding SUSE kdump initrd (RHBZ#1465849).

[Richard W.M. Jones]

The ‘vmware-uninstall-tools.pl’ script tries to rebuild the initrd.
On SUSE, if kdump initrd has been enabled, this hangs because the
‘mkdumprd’ doesn't know what root device to use.  Fix that by setting
the ‘rootdev’ environment variable.
