Include parser tests in the test-all.sh script.

Move test-all.sh to the top level directory, and also run the parser tests from
this script.

Use a release build of cton-util to run the parser tests. As we accumulate many
tests in the tests directory tree, this will mean they can still be run quickly.

Point Travis config to the new test script.
