syscalls/core, syscalls/x86: Rename struct pt_regs-based sys_*() to 
__x64_sys_*()

This rename allows us to have a coherent syscall stub naming convention on
64-bit x86 (0x prefix removed):

 810f0af0 tkernel_waitid# common (32/64) kernel helper

 __do_sys_waitid# inlined helper doing actual work
 810f0be0 t  __se_sys_waitid# C func calling inlined helper

  __do_compat_sys_waitid# inlined helper doing actual work
 810f0d80 t   __se_compat_sys_waitid# compat C func calling inlined helper

 810f2080 T __x64_sys_waitid# x64 64-bit-ptregs -> C stub
 810f20b0 T__ia32_sys_waitid# ia32 32-bit-ptregs -> C stub[*]
 810f2470 T __ia32_compat_sys_waitid# ia32 32-bit-ptregs -> compat C stub
 810f2490 T  __x32_compat_sys_waitid# x32 64-bit-ptregs -> compat C stub

[*] This stub is unused, as the syscall table links
__ia32_compat_sys_waitid instead of __ia32_sys_waitid as we need
a compat variant here.
