hexagon: signal: switch to SYSCALL_DEFINE0 for sys_rt_sigreturn()

Clang warns:

  arch/hexagon/kernel/signal.c:223:16: warning: no previous prototype for function 'sys_rt_sigreturn' [-Wmissing-prototypes]
    223 | asmlinkage int sys_rt_sigreturn(void)
        |                ^
  arch/hexagon/kernel/signal.c:223:12: note: declare 'static' if the function is not intended to be used outside of this translation unit

  1 warning generated.

Switch to the SYSCALL_DEFINE0() macro, which automatically declares a
prototype.
