[tlbuild] dvips rebuild please

[Karl Berry]

Hello one more time TL builders,

I just committed (r50901) a fix (I hope; below) for the bug that Arnaud
reported with invoking dvips on long file names.
https://tug.org/pipermail/tex-k/2019-April/003011.html

If anyone sees problems with it, let me know.
Akira, I did not separate out the ) into its own cmdout call because
then there is a newline before the ) in the output file.

I think this is worth pushing out, so please rebuild. Nothing else has
changed, so dvips should be the only new binary. --thanks, karl.
