[pkg-apparmor] Bug#882070: apparmor: AppArmor should allow to read /etc/pulse subdirectories

[Vincas Dargis]

Relevant NEWS entry:

```
pulseaudio (11.1-2) unstable; urgency=medium

   * Since this version, pulseaudio disables autospawn by default on linux
     systems, and replaces that with systemd socket activation. If you are not
     using systemd, then please edit or remove
     /etc/pulse/client.conf.d/00-disable-autospawn.conf
     to reenable it.
