owncloudclient: update to 2.8.2.
#### Have the results of the proposed changes been tested?
- [X] I use the packages affected by the proposed changes on a regular basis and confirm this PR works for me

One test fails, but I believe it was failing before.

I had to add a trivial patch which I reported upstream (https://github.com/owncloud/client/pull/8684).

NOTE: without the patch, even the current version (2.7.1_2) fails to compile.

A patch file from https://github.com/void-linux/void-packages/pull/31315.patch is attached
