Race condition between do_compile_kernelmodules and do_shared_workdir

while do_shared_workdir tries to copy them to shared working directory.
Functionality of do_shared_workdir has been moved to separate function
mk_shared_workdir and called from do_kernel_compile. do_shared_workdir
left in the code as it may be used in many recipes.
Looks good. Thanks for the respin of the patch! I'll put my
variant in the attic, since this looks like it will solve
the issue.
Cheers,
