Change i386 minimum processor from 586 to 686

We will stop supporting 586 processors in stretch, so update the i386
hardware requirements accordingly.

Remove the note about the 586 flavour not supporting SMP.  Both the
remaining i386 kernel flavours do support it.

As no 686 systems support VLB nor use ISA or EISA as the main bus,
remove those from the list of busses.

Change the preseed example to use the 686 kernel flavour.
