Fix instructions for running conformance tests

- The server-servlet app depends on mcp, which must be either installed
  or included in the compile artifact for `mvn exec:java` to pick it up.
- Change the build instructions to build from root, use a `-pl` flag to
  target the servlet app.
- Disable the exec plugin from the root pom.
