Subject: [PATCH] riscv: sigcontext: Correct the comment of sigreturn

From: Guo Ren <guoren@...ux.alibaba.com>

The real-time signals enlarged the sigset_t type, and most architectures
have changed to using rt_sigreturn as the only way. The riscv is one of
them, and there is no sys_sigreturn in it. Only some old architecture
preserved sys_sigreturn as part of the historical burden.
