python3-grako: fix permissions
@sgn 

chmod +r files in Python3 site-packages to make them world/other
readable.

Currently the files are installed with the following permissions:

```
ll /usr/lib/python3.8/site-packages/grako-3.99.9-py3.8.egg-info/
total 36K
-rw-r----- 1 root root  11K Sep 27 00:09 PKG-INFO
-rw-r----- 1 root root 3.1K Sep 27 00:09 SOURCES.txt
-rw-r----- 1 root root    1 Sep 27 00:09 dependency_links.txt
-rw-r----- 1 root root   38 Sep 27 00:09 entry_points.txt
-rw-r----- 1 root root    1 Sep 27 00:09 not-zip-safe
-rw-r----- 1 root root   22 Sep 27 00:09 requires.txt
-rw-r----- 1 root root    6 Sep 27 00:09 top_level.txt
```

This prevents programs such as `qutebrowser` from running.
