linux_sys_getdents64(): make the d_off member point to next entry, rather 

than current one; this is expected (even documented) behaviour of the
new system call
This fixes the endless loop when reading directories on NFS, though
applications won't see all directory entries due to different problem.
Fix by Matthias Scheler and Charles Hannum.
