yocto-check-layer: improve missed dependencies

The first 2 calls to add_layer_dependencies() are here to add all
dependencies for the 'layer under test' and the additional layers
provided by the users.

In both cases, we use misssing_dependencies boolean to indicate if any
dependency is missing. But we then never really use
missing_dependencies. Instead the script is calling
add_layer_dependencies() again (for both the layer under test, and the
additional layers) to detect if there are any missing dependency. As a
result, we are trying to add again all dependencies, and we can see
that from the traces:

INFO: Detected layers:
INFO: meta-aws: LayerType.SOFTWARE, /work/oe/sources/meta-aws
INFO: checklayer: Doesn't have conf/layer.conf file, so ignoring
INFO:
INFO: Setting up for meta-aws(LayerType.SOFTWARE), /work/oe/sources/meta-aws
INFO: Adding layer meta-python
INFO: Adding layer meta-oe
INFO: Adding layer meta-networking
-->
INFO: Adding layer meta-python
INFO: meta-python is already in /work/oe/poky/master/build-checklayer/conf/bblayers.conf
INFO: Adding layer meta-oe
INFO: meta-oe is already in /work/oe/poky/master/build-checklayer/conf/bblayers.conf
INFO: Adding layer meta-networking
INFO: meta-networking is already in /work/oe/poky/master/build-checklayer/conf/bblayers.conf
<--
INFO: Getting initial bitbake variables ...

The code appears more complex than it should, and we can simply
replace the complex if statement by using missing_dependencies, and
avoid duplicating the call to add_layer_dependencies().
