Update debian stage1 rsync options

Updated almost 3 years ago, cf.
https://salsa.debian.org/mirror-team/archvsync/-/merge_requests/2

The ref mentioned in the code is still good, so you can compare this MR
with what's currently in ftpsync:
https://salsa.debian.org/mirror-team/archvsync/-/blob/master/bin/ftpsync#L431
