 inkscape: fix build in High Sierra (maintainer timeout)

 The current version of Inkscape fails with a build error due to an
 ambigious call to abs(). Indeed, i->pathNext->id.objID is of type
 unsigned int, for which abs() does not make much sense. Adding a cast
 to 'long' fixes it.

 The root cause of the bug is likely that the code isn't strictly valid
 C++, and so the version of Clang included with Xcode 9 rejects it,
 where earlier versions of Clang accepted it. Since this is a build
 fix, we don't bump the revision.

 PR submitted two weeks ago, but the maintainer didn't respond.

 (Based on suggestion by Michael Lass)
