bionic-amd64-tf-m-build: Add cysecuretools to requirements_python3.txt

The cysecuretools is the tool to sign the binaries for Cypress PSoC6 [1]
psutil will be installed as a dependency package by pip3, so remove
python3-psutil from the PKG_DEPS
Some python3 packages version are adjusted, due to the requirement of
cysecurtools
