Use wide character API to get current directory on Windows.

* liboctave/system/lo-sysdep.cc (octave::sys::getcwd): On Windows, use wide
character API to get current working directory and convert to UTF-8. This partly
fixes a regression that prevents executing any commands if the current working
directory contains non-ASCII characters.
