Update to jnr-posix 2.3.3 release.
Fix issue #403.

Dir converts the filenames retrieved with glob to utf8, which causes issues when the filenames are not assumed to be utf8 and encoded again into utf8.  This fix ensures the RubyString created from the matched ByteLists are treated as utf8 so that they are not converted again.
Add Unicode file in special folder for test.
