reproducibility: mark libbotan as known non-reproducible

libbotan packages are not reproducible.

Quick analysis: A path in /usr/lib/libbotan-3.so.7.7.1 changes:
-/etc/ssl/ca-bundle.pem
+/etc/ssl/certs/ca-certificates.crt
Look like the trusted TLS CA store full path. This path most likely
changes depending on host OS.
