package: Add support for kernel stripping

Browse Source 
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.

(From OE-Core rev: e09a8fa931fe617afc05bd5e00dca5dd3fe386e8)
