Convert external/hyphenation-patterns to Android.bp

In order to reflect license for each locale precisely, add Android.bp to
every build in locale folder and due to combine .hyb and .lic.txt to a
single soong module name 'hyph-*', also modified PRODUCT_PACKAGES from
both hyph-$(locale) and hyph-$(locale).lic.txt to hyph-$(locale) only.
