image.bbclass: don't emit redundant IMAGE_CMD_xxx functions

IMAGE_CMD_xxx commands are always inlined within do_image_xxx.

When IMAGE_CMD_xxx is defined as a function (e.g. IMAGE_CMD_btrfs,
IMAGE_CMD_cpio, etc), a redundant copy of the function will be emitted
by default. Remove IMAGE_CMD_xxx 'func' flags to prevent that.
