dev-manual/layers.rst: yocto-check-layer: mention --machines and --dependency

The yocto-check-layer script should be run with the --machines arguments
to test the different machines present in a BSP layer. Mention it in the
documentation. The --dependency can also be used so also mention that.

 Be sure to provide the actual directory for your

+You should pass the dependencies of your layer using the ``--dependency``

 Entering the command causes the script to determine the type of layer
