If uhttpd is started with the option -M then Last-Modified header is not send during ok respond. We have already an ETag header set which is more accurate.
See URL: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Etag So make sending of Last-Modified header optional with a config option. If the option is not set then the behaviour is as before this option was added.
