  (WIP) Support EFI on 32bit systems, increase EFI image size + switch from isohybrid to xorriso/isohybrid combination

EFI on 32bit systems is a requested feature for Grml-Forensic,
since cheap tablets and notebooks are out there with 32bit EFI,
even though the system might be 64bit then.

Increase EFI image size (previously automatically
calculated on-demand, resulting in ~285KB) to 4MB,
giving us more flexibility with what we're installing
into the image (esp. useful with usage on USB drives).

The isohybrid binary doesn't support 32bit FI systems
and fails hard when using `--uefi` on a 32bit ISO.
But xorriso with appropriate options for EFI usage
(see $EFI_ARGS) and /usr/lib/ISOLINUX/isohdpfx.bin
from the isolinux package seems to provide everything
we need.
