l10n.eclass: Disabled locales are the complement of enabled ones.

Disabled locales returned by l10n_get_locales() should be the
complement of enabled locales: disabled = PLOCALES \ enabled.

So far, in the case of the enabled set falling back to PLOCALE_BACKUP,
the backup locale would end up being both enabled and disabled.
