appsrc: Do not override buffer caps if appsrc caps is null
Make appsrc not set caps on buffers when its own caps is NULL. This avoids calling make_metadata_writable on all buffers and prevents losing buffer caps in case we are not replacing it with something meaningful. https://bugzilla.gnome.org/show_bug.cgi?id=630353
