boot: Fix UUU tagging, extend to fslc

Using the UUU-tagged bootloader image directly with UUU can cause UUU to hang. The bootloader image is split on a certain transmit size, and the hang occurs if the tag does not fit with the final bytes of the bootloader image and must be split into a new transmit package. The UUU tag is needed by UUU only in the SD Card image file itself so that UUU can find the end of the boot partition. Rework the design so the default bootloader and the default imx-boot binaries are not tagged. Also, extend the UUU tagging to fslc so it can gain the same benefit. Fixes: #1762 Fixes: nxp-imx/mfgtools#416 Signed-off-by: Tom Hochstein <tom.hochstein@nxp.com>
