Userland: Use more common WAV MIME type

There is no official IANA MIME type for WAV (see
https://www.iana.org/assignments/media-types/media-types.xhtml#audio),
so this will always be subjective. While
https://www.rfc-editor.org/rfc/rfc2361 suggests audio/vnd.wave, we use
audio/wav since that seems to be most common across the internet.
