gen_initramfs.sh: create_initramfs(): Move and unify validation of --compress-initramfs-type to determine_real_args()
This will allow us to error out early if required user space tool
needed to compress initramfs based on specified --compress-initramfs-type
is missing or selected type is invalid/unsupported.
Best/fastest list is based on results from [Link1][Link2][Link3].
