curses: Fixes compiler error that complain don't have langinfo.h on msys2/mingw

Browse source 
msys2/mingw lacks the POSIX-required langinfo.h.

gcc test.c -DNCURSES_WIDECHAR -I/mingw64/include/ncursesw -pipe -lncursesw -lgnurx -ltre -lintl -liconv
test.c:4:10: fatal error: langinfo.h: No such file or directory
    4 | #include <langinfo.h>
      |          ^~~~~~~~~~~~
compilation terminated.

So we using g_get_codeset instead of nl_langinfo(CODESET)
