Adhemerval Zanella 0fcc93bce9 Mark lseek/llseek as non-cancellable
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.
