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

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

.../glibc$ grep_glibc_prototype iconv
iconv/iconv.h:42:
extern size_t iconv (iconv_t __cd, char **__restrict __inbuf,
		     size_t *__restrict __inbytesleft,
		     char **__restrict __outbuf,
		     size_t *__restrict __outbytesleft);
