makecontext.3: SYNOPSIS: Use 'restrict' in prototypes 

Both POSIX.1-2001 and glibc use 'restrict' in swapcontext().
Let's use it here too.

.../glibc$ grep_glibc_prototype swapcontext
stdlib/ucontext.h:41:
extern int swapcontext (ucontext_t *__restrict __oucp,
			const ucontext_t *__restrict __ucp)
  __THROWNL __INDIRECT_RETURN;
.../glibc$
