[mach-o] Fix lazy binding offsets

The way lazy binding works in mach-o is that the linker generates a helper
function and has the stub (PLT) initially jump to it.  The helper function
pushes an extra parameter then jumps into dyld.  The extra parameter is an
offset into the lazy binding info where dyld will find the information about
which symbol to bind and way lazy binding pointer to update.
