mac: Fix crashpad_snapshot_test ProcessReaderMac.Child*Thread* for 10.14

pthread_threadid_np() reports an incorrect thread ID after fork() on
macOS 10.14 (“Mojave”). See https://openradar.appspot.com/43843552. As a
workaround, use thread_info(…, THREAD_IDENTIFIER_INFO, …).

This uses MachThreadSelf(), which in turn uses pthread_mach_thread_np(),
which does not suffer from the same bug. As an alternative,
base::mac::ScopedMachSendRight(mach_thread_self()) could be used.

Bug: crashpad:249
