Subject: xtask: replace "lint" command by a simply cargo alias

This strips the run_clippy implementation out of xtask and replaces it by
a simple "cargo lint" alias which runs clippy with the corresponding flags.

Unfortunately  I could not name the alias "clippy" because that would lead to infinite recursion.
