Detecting the NXG ARM kernel version is easy because the kernel is installed the same way as on x64, only uncompressed (uImage). For older ARM NILRT however on-disk kernel version detection is harder because the kernel is compressed and stored inside an u-boot "itb" image alongside it's device tree, ramdisk and a bootscript, so we need to extract it and decompress. Make the distinction between older vs newer NILRT useing the new lsb_distrib_id grain which recently got repurposed in NILRT. Signed-off-by: Ioan-Adrian Ratiu <email@example.com>
