Re: luatexdir/luaoutputdir.test non-deterministic test failure

Hi Maxim,

    mkdir: cannot create directory
    ‘tests/outdirlua’: No such file or directory

Thanks for the report. I added a mkdir tests to that test (r76316). It
was random for the usual reason - many other tests already did the
mkdir, so it would depend on what ran first. Hopefully this will fix it.

(I'm surprised mkdir -p is portable enough, but all the other places
that do this use it unconditionally, so following suit here.)

Luigi, see my diff below for your upstream. --thanks, karl.
