flasher: heimdall-isorec: use kernel+dtb, support kernel suffix in deviceinfo parser
Use the dtb-appended kernel file, e.g. postmarketos-exynos4-dtb instead of postmarketos-exynos4, if it is available. This is needed to flash a mainline kernel with appended dtb to isorec devices.
Parse kernel suffix in deviceinfo files, and add pmbootstrap deviceinfo_parser
to manually verify that the parser works as intended.
