[PATCH 10/16] arch: x86: kernel: Add prototype for function sys32_x32_rt_sigreturn

[Darshana Padmadas]

signal.c defines the function sys32_x32_rt_sigreturn, which is
used in this file and some assembly. So add a prototype for the
function.

This eliminates the following warning:
arch/x86/kernel/signal.c:784:17: warning: no previous prototype for âsys32_x32_rt_sigreturnâ [-Wmissing-prototypes]
