Add patch to accept webdav backendsdebian/latest

As of 98b885f3, endeavour supports webdav backends from gnome-online-accounts.
This commit is on main, but hasn't been released yet. Therefore, it is not on
Debian stable.

This relies on gnome-online-accounts exposing webdav, which it already does on
Debian stable.

Between the previous release and this commit, there were some filename changes.
I modified the upstream diff to point to src/plugins/eds/gtd-plugin-eds.c
instead of src/engine/gtd-engine.c. Otherwise, the patch is the same.
