fix range check for Hangul jamo trailers in Unicode normalization
* lib/unicode_normalize/normalize.rb: Fix the range check for trailing Hangul jamo characters in Unicode normalization. Different from leading or vowel jamos, where LBASE and VBASE are actual characters, a value equal to TBASE expresses the absence of a trailing jamo. This fix is technically correct, but there was no bug because the regular expressions in lib/unicode_normalize/tables.rb eliminate jamos equal to TBASE from normalization processing. * test/test_unicode_normalize.rb: Add preventive test test_no_trailing_jamo based on https://github.com/python/cpython/commit/d134809cd3764c6a634eab7bb8995e3e2eff14d5 just for the case we ever get a regression. This closes issue #14934, thanks to MaLin (Lin Ma) for reporting. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64087 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
