Speed up integration tests (move building expectations)

Speed up running 'cargo test':
-Before: 2'17s
-After: 30s

Update to use new path:
Makefile, .travis.yml, CONTRIBUTING.md, tests/tests.rs

Delete unused expectation that fail to compile:
tests/expectations/moar_bitfields.rs
tests/expectations/variadic_template_args.rs

For every 'cargo test' run, the bindgen output where built.
We already test that the bindgen output match expectations/*.rs,
so there is no need to check it build unless the expectation is updated.

Move tests/expectations/*.rs to tests/expectations/tests/*.rs and make
tests/expectations a new dev-dependency package. This allow running:
 - cargo test -p tests_expectations

In addition to the speed up, we also get a clean output for the build
and test run. In particular, a number of warnings are generated that should
probably be silenced, and eventually enforced modifying travis to build:
 - RUSTFLAGS='-D warnings' cargo test -p tests_expectations

The benefit of having it as a new package is that it avoid polluting
the 'cargo test' output that should focus on bindgen.
