kernel.bbclass: Add shared_workdir_prepare task

The task do_compile_kernelmodules runs after the shared_workdir and
is installing some files in STAGING_KERNEL_BUILDDIR, this can races
in other recipes that depends on "virtual/kernel:do_shared_workdir"
as the STAGING_KERNEL_BUILDDIR is not fully populated when the
shared_workdir task ends.

To address this issue a new task is added in place of the previows one
so the shared_workdir will run after the do_compile_kernelmodules and
the new shared_workdir_prepare will replce of the old shared_workdir.
