rust: move rustfmt.toml to repo root so it can be used by `hg fix`
`hg fix` runs the formatters from the repo root so it doesn't pick up
the `rustfmt.toml` configs we had in each the `hg-core`, `hg-cpython`,
and `rhg` packages, which resulted in warnings about `async fn` not
existing in Rust 2015. This patch moves the `rustfmt.toml` file to the
root so `hg fix` will use it.
By putting the `rustfmt.toml` file in a higher-level directory, it
also applies to the `chg` and `hgcli` packages. That makes
`test-check-rust-format.t` fail, so this patch also applies the new
formatting rules to those packages.

Ensure debuild doesn't run the testsuite, as that could get silly.

We check debian package contents with portable tools so that when
we're on non-debian machines we can still test the packages that are
built using docker.
main deb should have .so but no .py
