x32: Add <fixup-asm-unistd.h> and regenerate arch-syscall.h

Browse Source 
X32 uses the same 64-bit syscall interface for set_thread_area.  But
__NR_set_thread_area is missing from <asm/unistd_x32.h>.  A kernel patch
was submitted:

Subject: [PATCH] x86-64: Enable x32 set_thread_area

X32 uses the common 64-bit syscall interface for set_thread_area.  Add
<fixup-asm-unistd.h> to provide __NR_set_thread_area.
