[tlbuild] pretest begin -> commit binaries

[Karl Berry]

Hi everyone - I've done the pretest setup. So please commit your 2022
binaries to the trunk at your convenience, including asymptote, or send
me urls as usual.  (I'll commit Mojca's and Norbert's auto-built ones.)

Luigi made a change to LuaTeX earlier today, so please be sure your
luatex --credits 
  ends with
Development id: 7499
and not 7495.

Thanks,
Karl
