travis: build sources with tracing enabled Our tracing architecture is not built by default, causing the Travis CI to not execute some code and skip several tests. As AppVeyor has already enabled the tracing architecture when building the code, we should do the same for Travis CI to have this code being tested on macOS and Linux. Add "-DENABLE_TRACE=ON" to our release-build options of Travis. (cherry picked from commit 8999f6acc78810680f282db4257e842971b80cb4)
