Avoid separate cache for integration tests

Browse source 
Travis uses [several factors](https://docs.travis-ci.com/user/caching/#caches-and-build-matrices)
to determine whether a given job shares a cache with a different job. In
particular, it uses any environment variables specified in
`.travis.yml`. Previously, integration tests set `INTEGRATION=true`,
which meant that the integration tests did not share a cache with the
non-integration tests, even though the compilation is exactly the same.

This patch fixes that by remvoing the `INTEGRATION` environment variable
and instead using the globally available
[`$TRAVIS_BUILD_STAGE_NAME`](https://docs.travis-ci.com/user/environment-variables/#default-environment-variables)
to run the setup required for integration tests only in stages that run
integration tests (namely integration and coverage). Now, the test and
integration stages share all the parameters that Travis uses to
determine cache identifiers, and so they'll share their cache!

Coverage still uses its own cache because it specifically needs to *not*
cache the compiled crate, but *does* need to cache `cargo-tarpaulin`.
