Sefa Eyeoglu 0aaf428fde nixos/postgresqlBackup: add --rsyncable to compression programs ...

The --rsyncable option changes the behavior of gzip/zstd so that the
resulting files can be incrementally backed up easily. Tools like Borg,
rsync and xdelta can make use their deduplication/diff mechanisms more
easily.

In my local testing, this resulted in a 2% size increase for backup
files.
