Hans-Christoph Steiner fd24416f4e switch serverwebroot rsync to --archive for guaranteed full sync
In `fdroid server update`, the rsync command used --update, which
`man rsync` says: "skip files that are newer on the receiver".  That could
cause issues of the public repo getting out of sync with the private,
master repo.  --archive is a better sync method since it aims to exactly
reproduce the sending dir to the receiving dir.
