kernel.bbclass: use common strip()

Browse Source 
Re-use the runstrip() code from oe.packaging, for the kernel
stripping process. Since runstrip() is python the kernel do_strip()
need to be converted to Python also. The stripped kernel image
will be used for deployment in do_deploy(). This will allow the
package.bbclass to split an unstripped kernel binary for the debug
information and extended packagedata. The extended package data is
used by create-spdx.
