Subject: [PATCH] travis: Only run cargo-audit on stable
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

… since there's no benefit in running it multiple times and cargo-audit
can't be built with older versions of rustc (at the time of writing,
cargo-audit has a minimum rustc version of 1.36.0)
