Subject: [PATCH] tests: don't enforce NS management support for local testing

The tests framework added supported and dependency on NS management for
clean setups. Though this prevents to run part of the tests suites on
devices which do no support NS management.

Add feature detection and skip the setup/tear down code for the NS
setup if the device doesn't support this.
