tests: Honour NO_YAML make variable

Support for YAML output in dtc is optional (to cover systems that don't have libyaml). Currently the tests for yaml output test if the libyaml package is locally installed. That duplicates similar logic in the Makefile, and worse it will cause failed tests if the user explicitly disables YAML support, rather than simply not having libyaml installed. Fix this by having the test script use the NO_YAML variable exported by make. Fall back to the current test if the variable isn't set, such as when running the script manually.
