Update to latest runtime (#100)

- Bump runtime library to version that integrates the ghūl port of the pipes library
- Bump compiler tool to version that supports pipes integrated into the ghūl runtime library

Notes: the compiler integration tests reference the runtime library that's packaged with ghul-test, so we need to take the runtime package update here before the compiler can also take it.
