You can blow away /kern.GENERIC for now and once you are upgraded you
can blow away /kernel.  5.0 puts kernels in /boot/<kernel name> and
each kernel includes its own set of modules rather than having
/<kernel name> and a set of shared modules under /modules.  You can
also blow away modules you aren't using in /modules right now and
once the installworld is done blow away all modules in /modules that
aren't 3rd party modules.
