Replace abs() on unsigned arguments in lang/beignet

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

/wrkdirs/usr/ports/lang/beignet/work/Beignet-1.1.1-Source/backend/src/backend/gen_insn_selection.cpp:1156:27: error: call to 'abs' is ambiguous
    insn->extra.longjmp = abs(index - origin) > 800;

This is because abs() is being called with unsigned arguments.  Fix this by calculating the unsigned difference in a safe manner.
