Kill mac68k *SBC kernels. Instead, build kernels with both sbc scsi flavours

compiled in, but one disabled, and use config -e to swap them and build
the other kernels; saves valuable compile time.
Add ramdisks into the build (at release time). Since we are moving to a
bsd.rd installation, it is not necessary to put kernels in .tgz files
anymore, so don't bother, and adjust installation script sets information
accordingly.
