[tex-live] scheme minimal and broken softlinks

[Karl Berry]

    minimal scheme (nice and fast)

If you don't actually need to run any TeX, scheme-infraonly is faster
yet :).

    all pointing to the missing 
    xdvipdfmx

Thanks, I added the xdvipdfmx binary to the dvipdfmx package, where it
should have been quite a while ago, when the *fmx link setup was
constructed.

    not sure they are suppose to be there since mianimal ought to be
    just plain

scheme-minimal has always included both dvips and dvipdfm(x), among
other driver-related things ... --thanks, karl.
