While building unified-deb we first use scylla/reloc/build_deb.sh to create the scylla core package, and after that scylla/reloc/python3/build_deb.sh to create python3. On 058da69#diff-4a42abbd0ed654a1257c623716804c82 a new rm -rf command was added. It causes python3 process to erase Scylla-core process. Set python3 to erase its own dir scylla-python3-package only.
