[TSan] fix the module map of main executable on darwin platforms (#107227)

In the executable image on Darwin platforms, there is a `__PAGEZERO`
segment with a size of 0. When calculating the module map, this segment
must be skipped to avoid errors. The previous implementation
inaccurately calculated the executable image's range, starting the
address at `0 + slide`.
