Added several tests for locale support (8 bit and multibyte UTF-8)

Basically all tests have been taken from glibc. For testing multibyte encoding
EUC_JP parts have been commented out and added new section for UTF-8
that is the only multibyte  codeset currently supported on uCLibc.

Some tests are still failing due to unsupported/missing features, other have been
fixed.
