kernel.bbclass: Fix race condition
Race condition between do_compile_kernelmodules and do_shared_workdir
tasks occurs when do_compile_kernelmodules changes files in
include/generated/* while do_shared_workdir tries to copy them to
shared working directory.
Fixed race by moving do_shared_workdir after do_compile but before
do_compile_kernelmodules.
