Additions/linux/installer: build new kernel modules on system stop. bugref:3809: Linux installer maintenance With this change, we stop trying to use the DKMS hooks to rebuild kernel modules, as they have proved too unreliable to be useful. Instead we now simply rebuild for new kernels found at shutdown time, and again on start-up in case there was a hard shutdown. Also clean up quite a bit of shell script and improve the udev detection.
