run_formatter.sh: Warn if `rustfmt` is not installed.

My workstation didn't have `rustfmt` installed, which resulted
in weird cargo errors when running the script. This changes
it to check for `cargo fmt --version` first before trying
to run it, and print a warning otherwise.

+ Fix a series of issues reported by shellcheck, by using
  better quoting an array variables to manage lists.
