bin: Squash some -Wuninit warnings with porting to new style

I noticed this with a local build of an RPM:

```
/usr/include/glib-2.0/glib/glib-autocleanups.h:28:3: warning: 'help' may be used uninitialized in this function [-Wmaybe-uninitialized]
   g_free (*pp);
   ^~~~~~~~~~~~
src/ostree/ot-main.c:82:20: note: 'help' was declared here
   g_autofree char *help;
                    ^~~~
```

Closes: #1091
