image_types.bbclass: Make u-boot signed images more versatile

With the introduction of chaining compression/conversion support we can
convert the old image_types_uboot.bbclass code that did a hand-chaining
of a set of ${filesystem}.${compression} into generic and arbitrary
support to sign whatever the user wants to sign for their image.

This, for the record, does remove setting a valid compression type in
the record in favour of just saying none.  This is not a generally
useful feature in U-Boot and I believe being versatile in terms of being
able to pass in arbitrary compressions is more important.
