tdf#138481: Trust the built-in break iterator character data in ICU

Don't use our own char.txt.

the char_in.txt hasn't really changed since 2008 and is woefully out of
date at this point.

we have cppunit tests for the only documented bug that touched
char_in.txt, #i111152# and tdf#40292, for tdf#40292 change the test
to test what was actually reported as a bug
