bitbake: toaster: layer-relative paths for config files

Change bitbake variables table to show the path to the file in which
the variable was defined using a layer-relative path instead of the
full path to the file.

The layer-relative path is found by matching on the full defining file
path with entries in a list of layer names, sorted in descending order,
and with 'meta' appended as a built-in layer to the end of the list.

Additional filters are used to reduce false matches, although even if
there is a false match, the actual path to the defining file will be
obvious and not misleading.
