image_types: fix squashfs-lzo and squashfs-xz builds
Dependencies required for squashfs-lzo and squashfs-xz image builds were
assigned to do_image_squashfs-lzo and do_image_squashfs-xz. As these
tasks don't exist the dependencies were not installed and builds
were failing.
Correct task names for these image types are: do_image_squashfs_lzo and
do_image_squashfs_xz because '-' and '.' are replaced by '_' in all
do_image* task names.
