Fix routing configuration

- Something changed somewhere along the way, and DefaultRouteMatcher
  became more strict in what it accepts for filters (it only accepts
  FilterInterface implementations, not any callable). As such, updated
  zf-deploy configuration to wrap the `$booleanFilter` in a `Callback`
  filter.
- Also, the tests were brittle, and were not managing the auto-prefixing
  of the build command properly. As such, added "build" back into the
  build route, fixing the test issues.
