Register default signal handler

When the .NET Runtime receives SIGABRT and the previous handler is the default handler,
the .NET Runtime restores the default handler as the current handler and continues.

As a result, if a signal handler has not been registered before the .NET Runtime,
the application will be terminated only after calling SIGAGRT twice.

To avoid this situation, add signal handler before coreclr_initialize()
