bitbake: cooker/cache: Drop mc 'default' string value

The string value "default" for the default multiconfig is confusing since an
empty string is used pretty much everywhere in the code. Remove the few
remaining references to that to standarise.

This affects the default value of BB_CURRENT_MC and does have an impact
on metadata, particulalry bitbake.conf in openembedded-core. That said, the
number of bugs we'll avoid by trying to make "default" back to "" within
bitbake's code make fixing those extremely worthwhile.
