[tlbuild] dvisvgm-2.1 trial build

[Richard M. Koch]

Karl,

Am upstream fix is best. Thanks for doing this.

We'll actually build TeX Live 2017 on OS X 10.10, Yosemite. So I decided to try
compiling there as well as the current Sierra. With my small patch,
everything compiled without error, and passed all tests.
