build: rsync buildlogs to <webroot>/repo
Had a discussion with @eighthave about what we need to do for deploying full build-logs of our productions system. The outcome was what I implemented in !515 (merged) is mostly okay. (
deploy_process_logs = True). Just the deployment path need to be updated. So that's this MR.
I also did a end-to-end test having my contributor-vm deoloy to our staging website. Works as expected. (file will probably disappear when staging re-deployes: https://staging.f-droid.org/repo/org.fdroid.fdroid_16.log.gz)
