Description:
Added respawn to procd parameters with default options.

Sometimes mdns-repeater quits or crashes, leaving service stopped, requiring manual (re)start. This commit should fix that – and I use this patch this on all my openwrt routers for nearly a year.

Hey @axkg, could you perhaps merge this? Seems like some checks require a review, and unfortunately for some reason I can't request it...

[axkg]

Not sure why I see two commits, in any case I approved both but I lack write access as well. @1715173329: Would you be so kind to merge this PR?
