x86: headers cleanup - prctl.h

Browse Source 
Impact: cleanup (internal kernel function exported)

'make headers_check' warn us about leaking of kernel private
(mostly compile time vars) data to userspace in headers. Fix it.

sys_arch_prctl is completely removed from
header since frankly I don't even understand why we
describe it here. It is described like
__SYSCALL(__NR_arch_prctl, sys_arch_prctl) in unistd_64.h
and implemented in process_64.c. User-mode linux involved?
So this one in fact is suspicious.
