package: Add support for kernel stripping
Extend runstrip() to accept additional argument to enable sharing it with the kernel do_strip() so that KERNEL_IMAGE_STRIP_EXTRA_SECTIONS can be passed. Since is_elf() understands kernel modules there is no need to keep a seperate list for kernmodules or hardcode the values to runstrip.
