Subject: [PATCH 2/2] perf build: Add Debian/Ubuntu python-is-python3

The build looks for "python" and "python-config", while modern
distributions provide only "python3" and "python3-config" by default.
Suggest installing "python-is-python3" and "python-dev-is-python3", as
available on Debian 11 (bullseye) and Ubuntu 20.04 LTS (focal) and
later.
