Fixes for thai linebreaking

* Load libthai.so.0 since libthai.so is not there on all systems
* Remove dependency on codecs. Unicode->TIS620 is so simple we can
simply hardcode it in harbuzz-thai.c
* Speed up detection of word boundaries
* Falback when libthai is not found is now to not break instead of
breaking after every character (in line with recommendations from
unicode.org linebreaking algorithm)
