File catch_invalid_initrd_path.patch of Package virt-v2v

In some cases (specifically, SUSE grub2 environments) it is possible to
fail to update the block entries in device.map. In turn, this causes an
invalid path to be returned in perl-Bootloader code, which causes the
conversion to fail with the following message:

is_file_opts: is_file: is_file_stub: path must start with a / character

This patch prevents the problem by adding device.map (for /boot/grub and
/boot/grub2) to the list of configurations to remap, then adds a check
to ensure invalid paths are not passed to is_file_opts.
