Add dummy tools to help identify needed dependencies

After the introduction of RSS, I still found it hard to get dependencies on some common tools that are typically installed on the build host correct. Using the wrong version of tools like pkg-config, gdbus-codegen and dbus-binding-tool can cause build failures.

To circumvent this, I created dummy versions of the tools that always fail and placed them in the scripts directory. Thus, if the real tool has not been installed in the RSS, the dummy version is used and the build fails. For good measures I even output a message that says what needs to be corrected in the recipe.

Included is also an update to linux-libc-headers as it apparently needs to inherit pkgconfig, which the introduction of the dummy version of pkg-config showed.

PATCHv2: Also inherit pkgconfig in module.bbclass since pkg-config is needed for the make_scripts task.
