Fix rpi-sdimg after IMAGE_FSTYPE being enforced in poky-agl.conf

This changeset fixes the case of the rpi-sdimg which was broken
by the IMAGE_FSTYPE setting introduced in poky-agl.conf (distro-wide).

A new variable AGL_EXTRA_IMAGE_FSTYPES is available now and only used
in AGL (target) images.

Reasoning for this solution:
- any modifications to IMAGE_FSTYPES will also affect things like the initramfs or initrd images.
- we minimized the disk-space requirements by reusing the ext4.xz for the rpi-sdimg
