[tlbuild] one more time

Last-minute dvisvgm patch to handle communication with mupdf (per below).
Seemed important enough to do now instead of waiting. Please rebuild.
--sorry/thanks, karl.

the recent release fixes a bug that prevents the proper processing of 
PDF files via dvisvgm's new mutool-based PDF handler. The issue was 
reported by Bruno Voisin and occurred on a Mac only [1]. I wasn't able 
to reproduce it on Linux, but that could just be a happy coincidence 
since the affected code was indeed buggy.

As long as Ghostscript < 10.01.0 is present on the user's system, this 
isn't a big issue because the recent GS versions still come with the old 
PDF interpreter. As soon as GS 10.01.0 is used, dvisvgm needs its new 
PDF handler working. Otherwise, PDF files can't be processed.

That's the situation. I can't estimate how many TeX Live users would 
actually be affected by the bug. If you prefer to keep the current state 
of TL, that's fine from my end. In case there are special TL 
distributions that also provide the GS library, they maybe should 
consider keeping the recent GS version or apply patch [2] locally.

Best,
Martin
