u-boot-fslc: add support to build boot container for mx8m
U-Boot provides a possibility to build a boot container for i.MX8M derivaties, this is done via invoking a make target "flash.bin". Add this support to the recipe via inheriting the imx-boot-container class which extends U-Boot build system to construct flash.bin boot container.
