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

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

.../glibc$ grep_glibc_prototype strcpy
string/string.h:125:
extern char *strcpy (char *__restrict __dest, const char *__restrict __src)
     __THROW __nonnull ((1, 2));
.../glibc$ grep_glibc_prototype strncpy
string/string.h:128:
extern char *strncpy (char *__restrict __dest,
		      const char *__restrict __src, size_t __n)
     __THROW __nonnull ((1, 2));
.../glibc$
