devtool/standard: set a preferred provider when adding a new recipe with devtool

A recipe added with "devtool add" requires to be able to take precedence on recipes
previously defined with PREFERRED_PROVIDER.

By adding the parameter "--provides" to "devtool add" it is possible to specify
an element to be provided by the recipe. A devtool recipe can override a previous
PREFERRED_PROVIDER using the layer configuration file in the workspace.

E.g.
    devtool add my-libgl git@git://my-libgl-repository --provides virtual/libgl
