Network: Use QFile::encodeName for POSIX paths instead of toLatin1

Browse Source 
POSIX API doesn't really have defined encoding and kernel works with
null-terminated byte strings (char *) without any knowledge about
encodings.

But usually applications use LANG (and LC_*) as encoding making it
possible to use any encoding user wishes, including full Unicode
support when UTF-8 is used.

This allows to create and listen to sockets with paths containing
non-latin characters.
eg. listen(QString("/run/υποδοχή"));
