Previously building `//:noicu/mksnapshot` on M1 macs produced this
linker error:

```
Undefined symbols for architecture arm64:
  "v8::internal::trap_handler::TryHandleSignal(int, __siginfo*, void*)", referenced from:
      v8::TryHandleWebAssemblyTrapPosix(int, __siginfo*, void*) in libv8_libshared_noicu.lo(api.o)
  "v8::internal::trap_handler::RegisterDefaultTrapHandler()", referenced from:
      v8::internal::trap_handler::EnableTrapHandler(bool) in libv8_libshared_noicu.lo(handler-outside.o)
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
```

Because this branch that enabled the trap handler:

```
// Arm64 (non-simulator) on Mac.
 #elif V8_TARGET_ARCH_ARM64 && V8_HOST_ARCH_ARM64 && V8_OS_DARWIN
```

Wasn't handled in the build, so the file was excluded.
