Subject: [PATCH] aarch64: signal: fix type definition for ucontext_t.uc_link

When compiling the test program for libucontext, I observed a compiler warning
concerning assignment to the wrong type (`struct __ucontext` vs `struct ucontext`).
Accordingly, ucontext_t.uc_link should be the same structure as ucontext_t itself.
