{kernel, module}.bbclass: don't run depmod for module packages during do_rootfs
* depmod already gets executed by pkg_postinst_kernel-image.
* If you build a module using module.bbclass, pkg_postinst returns 1 in
do_rootfs, causing pkg_postinst to run again on first boot. To improve
this situation, I copied pkg_postinst from kernel.bbclass to module.bbclass.
This was rejected by Koen, because he doesn't like the code from
kernel.bblcass, which uses ${STAGING_DIR_KERNEL}. Richard then suggested
that calling depmod during do_rootfs wasn't necessary at all, because
it already gets done by kernel-image.
