Don't display bogus parameter for sigreturn syscall

* linux/*/syscallent.h: For those arches which use sys_sigreturn,
not printargs, to show [rt_]sigreturn syscall, change number of arguments
from 1 to 0: sys_sigreturn function doesn't use syscall parameters.
(I guess kernel doesn't actually _have_ any parameters for this syscall,
at least on these architectures). Do the same change for I386 and x86-64
even though they use printargs: I looked at kernel code and syscall
definitely doesn't have any parameters on these arches.
(I hesitate to change 1 to 0 params for arches I don't know -
it is remotely possible some of them do have a parameter for this syscall).
