Subject: tdf#123077 gtk3_kde5: Set KFileWidget's custom widget only once

Since the event filter is only used to set the custom
widget in the KFileWidget, it can and needs to be removed
again once this has been done; which also avoids crashes.

(s. https://gerrit.libreoffice.org/#/c/67185/ for more
infos, where the same thing is done for kde5)
