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

Both POSIX and glibc use 'restrict' for some of these functions.
Let's use it here too.

glibc:
=============================  fopen
libio/stdio.h:246:
FILE *fopen (const char *restrict filename,
                    const char *restrict modes) wur;
=============================  fdopen
libio/stdio.h:279:
FILE *fdopen (int fd, const char *modes) THROW wur;
=============================  freopen
libio/stdio.h:252:
FILE *freopen (const char *restrict filename,
                      const char *restrict modes,
                      FILE *restrict stream) wur;
