package_rpm: use zstd's default compression level

Browse Source 
zstd uses 3 by default, while 19 is the highest and slowest.
It's not clear why 19 was picked to begin with, possibly
I copy-pasted it from rpm's examples without thinking:

This brings significant speedups in rpm's compression step:
for example compressing webkitgtk takes 11s instead of 36s.

The rpm size increases from 175648k to 234860k. I think it's
a worthy default tradeoff.
