visrc: Move filetype detection to separate function

I hadn't noticed the `return;` line when a filetype match is found so
couldn't get my additions to this function to work. Moving the detection
to a separate function keeps that isolated and indicates that other
functions can be called from the same `vis.events.win_open` hook.
