Hi!
On x86_64 it matters how many arguments one declares for syscall.
sendfile has 3 args, scalar, scalar, pointer, scalar, yet it was declared
as i:iip, which means %rcx was not moved to %r10.
While at it, I've fixed a couple of other signatures too, full
review would be good some time.

* sysdeps/unix/sysv/linux/x86_64/syscalls.list (sendfile): Change
args to i:iipi.
(readahead): Change args to i:iii.
* sysdeps/unix/sysv/linux/powerpc/powerpc64/syscalls.list (readahead):
Change args to i:iii.
* sysdeps/unix/sysv/linux/mips/syscalls.list (readahead): Change
args to i:iiii.

Thanks, I put it in.
If we ever had an ABI checker, it would have this information for us.
