fix(inetutils)

clang on mac complaining something awful:

```
syslogd.c:281:7: error: conflicting types for 'ttymsg'
char *ttymsg (struct iovec *, int, char *, int);
      ^
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/util.h:103:9: note: previous declaration is here
char   *ttymsg(struct iovec *, int, const char *, int);
```

closes #4659
