dynamic_module_runner fails with dynamic module carries dependencies information

[akemimadoka]

For file test.dart:

import "dart:io";

@pragma('dyn-module:entry-point')
void main() {
  print(systemEncoding);
}

Compiles with command:

sdk/out/DebugX64/dart-sdk/bin/dartaotruntime sdk/out/DebugX64/dart-sdk/bin/snapshots/dart2bytecode.dart.snapshot --bytecode-options=annotations --platform sdk/out/DebugX64/dart-sdk/lib/_internal/vm_platform_product.dill test.dart -o test.dill

Runs with command:

sdk/out/DebugX64/dart-sdk/bin/dart sdk/pkg/dynamic_modules/bin/dynamic_module_runner.dart test.dill

Fails with:

../../runtime/vm/bytecode_reader.cc: 1584: error: expected: metadata.IsArray()
