Exclude PyDSDB library files
    
    Following library files are built without AD DC but has dependency on
    other components which are only available with DC:
    
    /usr/lib64/python3.9/site-packages/samba/dsdb.cpython-39-x86_64-linux-gnu.so
    /usr/lib64/python3.9/site-packages/samba/dsdb_dns.cpython-39-x86_64-linux-gnu.so
    
    Therefore we remove those from buildroot.
    
    resolves: #1991353
