[tex-live] getnonfreefonts doesn't work with pretest

[Karl Berry]

    TEXMFMAIN and TEXMFDIST point to the same
    directory and I suppose that former or later one of them will be
    removed but I don't know which one.

For myself, I don't see a reason to ever remove either one, precisely
because an indeterminate number of scripts can be using them.  It costs
nothing to keep them.

(That said, I am not arguing for you to change anything wrt
getnonfreefonts.)
