ioctl: use x32 specific ioctl entries on x32 personality

As ioctls_inc.h generated natively on x32 differs both from 32/ioctls_inc.h
(by 45 entries) and from linux/64/ioctls_inc.h (by 322 entries), use x32
specific ioctl entries on x32 personality.

* linux/x32/ioctls_inc0.h: Generate from linux v3.19 using ioctls_gen.sh.
* linux/x86_64/ioctlent2.h: Remove.
* linux/x86_64/ioctls_arch2.h: New file.
* linux/x86_64/ioctls_inc2.h: New file.
* Makefile.am (EXTRA_DIST): Remove linux/x86_64/ioctlent2.h, add
linux/x86_64/ioctls_arch2.h and linux/x86_64/ioctls_inc2.h.
