scripts/rsync-generation/mksnapshot: increase zstd compression level

grobian · grobian · commit bd139cb92950 · 2024-03-31T10:43:50.000+02:00
Using -9 we end up at 58MB, which is more than gzip2's 57MB.  So up the
level to -19 (the max, basically like how we configure the other
compressors too) to get 52MB, which is still much more than xz (48MB)
and lzip (47MB).
