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

Both POSIX and glibc use 'restrict' in realpath().
Let's use it here too.

.../glibc$ grep_glibc_prototype realpath
stdlib/stdlib.h:800:
extern char *realpath (const char *__restrict __name,
		       char *__restrict __resolved) __THROW __wur;
.../glibc$
