Ensure standalone server handles SIGTERM

[ijjk]

This copies our existing SIGTERM/SIGINT handling for the standalone server we output for outputStandalone to ensure ctrl + c works correctly with Docker.

x-ref:

next.js/packages/next/bin/next.ts

Lines 108 to 110 in 4634356

	// Make sure commands gracefully respect termination signals (e.g. from Docker)
	process.on('SIGTERM', () => process.exit(0))
	process.on('SIGINT', () => process.exit(0))
