Move integration tests into src/tools/tests.

The integration tests use both libcretonne and libreader, so moving them avoids
the circular dev-dependency.

Also go back to building everything under src/tools/target to avoid rebuilding
the libraries when cargo is invoked in different subdirectories. This speeds up
test-all.sh quite a bit.

Finally, skip the pure debug build. We build "cargo test" and "cargo build
--release" which should cover everything we need.
