st: Ignore filtered selection events not meant to our clipboard window

Other windows like the mutter Xwayland selection bridges might deal with
the clipboard, which would result in events visible on st-clipboard event
filters.

In order to avoid unintended results, ignore events that are not meant for
the clipboard window.
