[ffwd2] improve UEFI WA support for multipath

The workaround for UEFI systems where we switch from
red to redhat efi boot and fix mounting of the /boot/efi
does not work with multipath devices. The device and
partition are now determined from first efi device in
lsblk -O -P output and parted output against PKNAME.
