This patch sets lseek/llseek for 64-bit, MIPS n32, and x86_32 as non-
cancelable.  This make it consistant with 32-bit platform.

Tested on i686, x86_64, and x32.

	* sysdeps/unix/sysv/linux/mips/mips64/syscalls.list (lseek): Set as
	non-cancelable.
	* sysdeps/unix/sysv/linux/wordsize-64/syscalls.list (llseek): Likewise.
	* sysdeps/unix/sysv/linux/x86_64/x32/lseek.S (__libc_lseek64):
	Likewise.

This change seems simple and harmless.  It would be nice if it could be
tested, verified, and committed separate from the whole series.  If this
change standalone on trunk creates no test regressions, then please put
it in right away.

Alright, I will reran all make checks on the available platforms I have
access and commit this change.
