    bitbake: bitbake-layers: show-appends: add optional argument to limit package list
    
    Add ability to limit output per package:
    
    $ bitbake-layers show-appends m4
    === Matched appended recipes ===
    m4_1.4.17.bb:
      /home/mattsm/git/openembedded-core/meta-selftest/recipes-test/m4/m4_1.4.17.bbappend
    
    Useful for writing tools to process the output, and debugging
    bbappends for specific packages
