QFileSystemEngine/Unix: remove futimes related code

- futimes isn't a standard system call[1]:
«
This system call is nonstandard.  It was implemented from a specification
that was proposed for POSIX.1, but that specification was replaced by the
one for utimensat(2).

A similar system call exists on Solaris.

[2] https://pubs.opengroup.org/onlinepubs/9699919799/functions/futimens.html

- futimens is a standard system call[2], it's available on:
 - Linux: https://man7.org/linux/man-pages/man2/futimesat.2.html
 - FreeBSD: https://www.freebsd.org/cgi/man.cgi?query=futimens&sektion=2&n=1
 - OpenBSD: https://man.openbsd.org/futimens.2
 - QNX: https://www.qnx.com/developers/docs/7.1/#com.qnx.doc.neutrino.lib_ref/topic/f/futimens.html

So, remove futimes related code.
