Made '-b' work with BBCLASSEXTEND

When BBCLASSEXTEND is set, '-b' builds usually failed with messages
like

| ERROR: Parsing error data_fn virtual:native:<recipe>.bb and fn
<recipe>.bb don't match
|
|   File ".../bb/providers.py", line 47, in sortPriorities
|     priority = dataCache.bbfile_priority[f]
| KeyError: 'virtual:native:<recipe>.bb'

This patch fixes it and allows to specify the alternative class in a
way like

| ./bitbake -b virtual:native:<recipe>.bb

This patch was written to be so minimal as possible; variables should be
probably renamed to reflect their new meaning.
