bitbake: bitbake-layers: show-recipes: Select recipes from selected layer

Currently, show-recipes will show recipes from all configured layers.
Assume, meta-intel layer was added to conf/bblayers.conf.

Example of default $ bitbake-layers show-recipes:
core-image-rt:
  meta-intel           unknown (skipped)
  meta                 unknown (skipped)

Add -l/--layer to enable showing recipes from user selected layer.

Example: $ bitbake-layers show-recipes -l meta-intel
core-image-rt:
  meta-intel           unknown (skipped)
