fix uppercasing for U+A64B, CYRILLIC SMALL LETTER MONOGRAPH UK
enc/unicode.c: Add U+A64B to the special cases 03B9 and 03BC
at the end of onigenc_unicode_case_map (Bug #12990).
enc/unicode/case-folding.rb: Add U+A64B to the special cases
03B9 and 03BC. Add a comment pointing to enc/unicode.c.
Change warnings to exceptions for unpredicted cases,
because this would have been more easily noticed
(the warning was not noticed when upgrading to Unicode 9.0.0).
test/ruby/enc/test_case_comprehensive.rb: Remove temporary
exclusion of U+A64B from testing.
