fix: keep resource-qualifier form in the locale filters

The derived values are handed to aapt2's -c option, which takes Android
resource-qualifier form (pt-rBR, zh-rCN) rather than BCP-47 tags. AGP uses a
non-empty localeFilters collection verbatim: no validation, no transformation,
so pt-BR reached aapt2 and failed resource linking.
