linux-user: zero fstat buffer to initialize nsec fields
The fstat implementation does not initialize the nanosecond fields in the stat buffer; this caused funny values to turn up there, preventing, for instance, cp -p from preserving timestamps because utimensat rejected the out-of-bounds nanosecond values. Resetting the entire structure to zero fixes that. Signed-off-by: Ulrich Hecht <uli@suse.de> Signed-off-by: Riku Voipio <riku.voipio@iki.fi>
