Subject: ref(tools/perf-flamegraph): move to a proper shell script

I don't want to inline shell scripts inside nix configuration, as it
prevents me to use `shellcheck` to validate them for example.

The script is now moved into the tool directory, and is a tiny bit more
flexible, so that I can run it as my own user.
