The meson.build files for building the kernel modules directory could
be improved now that it is extracted from the EAL. For example, no
global processing is necessary inside the kernel folder, just need to
subdir to the appropriate bsd or linux folder to do the actual work.

NOTE: this patch depends upon patch #35336, to move kernel modules to
   a top-level "kernel" folder.
