    buildhistory.bbclass: add layer name to source recipe data
    
    It is useful to know which layer provided a given recipe and its
    binary packages.
    
    Many projects combine a number of layers and some of them
    also provide same recipe names in which case bitbake
    can prioritize between them. buildhistory can record
    the decision by saving the layer from where the recipe
    was taken from.
    
    Also, if a project is split to sub projects which maintain
    recipes in different meta layers, then meta layer specific
    summaries of e.g. disk usage can be calculated if
    source recipes meta layer name is recorded for example in
    buildhistory.
    
    If source layer is not in build history, then layer providing
    the recipe can be exported from build environment using
    'bitbake-layers show-recipes', but it takes a long time to execute
    since all recipes are parsed again and requires full source tree
    with correct build configuration.
    
    This patch exports the name of layer as configured in BBFILE_COLLECTIONS
    append of its layer.conf. 'bitbake-layers show-recipes' exports the
    meta layers directory path name. For several open source layers
    these are different, e.g. meta-openembedded/meta-perl/conf/layer.conf
    is perl-layer, poky/meta/conf/layer.conf is core,
    poky/meta-skeleton/conf/layer.conf is skeleton etc.
