Fix type for abs() calls in graphics/inkscape

During the exp-run in bug 208158, it was found that graphics/inkscape gives
errors with libc++ 3.8.0 [1]:

libavoid/connector.cpp:888:29: error: call to 'abs' is ambiguous
		COLA_ASSERT(abs(i->pathNext->id.objID - i->id.objID) != 2);
			    ^~~

This is because abs() is called with unsigned arguments.  Fix it by casting the
arguments to the appropriate signed types.
