Subject: [PATCH] Don't bother trying to unregister the "reporttelemetry" event
 listener

Note that both event-unbind methods are unused in MOZCENTRAL builds; see https://searchfox.org/mozilla-central/rev/48b6992e03fa66f77ac9688ba61c95d31a451bc1/toolkit/components/pdfjs/content/web/viewer.js#1864-1869
