all.sh: reorganize testing around deprecated features

build_deprecated combined the testing of deprecated features, and
testing of the build without deprecated features. Also, it violated the
component naming convention by being called build_xxx but running tests.

Replace it by:
* test_default_no_deprecated: check that you can remove deprecated
  features from the default build.
* test_full_deprecated_warning: check that enabling DEPRECATED_WARNING
  doesn't cause any warning from our own code.
