fix(apparmor): Fix access to openssl configuration

AppArmor denies access to openssl configuration files:
```
type=AVC msg=audit(1548516028.121:3031): apparmor="DENIED"
operation="open" profile="qtox" name="/etc/ssl/openssl.cnf" pid=12416
comm="qtox" requested_mask="r" denied_mask="r" fsuid=1000 ouid=0
```

Fix deny by including openssl abstraction.
