[PATCH] lib: Fix getdents64 syscall.

[Andrius Štikonas]

getdents64 syscall returns slightly different dirent struct.

* include/linux/x86_64/syscall.h (SYS_getdents): Remove define.
(getdents64): Add define.
* lib/linux/getdents.c (getdents): Prioritize getdents64 syscall.
* include/dirent.h (struct dirent): Adjust for getdents64 syscall.
