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 (0xffffffff prefix removed):
810f0af0 t kernel_waitid # common (32/64) kernel helper
<inline> __do_sys_waitid # inlined helper doing actual work
810f0be0 t __se_sys_waitid # C func calling inlined helper
<inline> __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.
