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.
