Update and optionally install apparmor profile (ricochet-im#549)

* Update usr.bin.ricochet-apparmor

needs access to /sys/devices.../config for some graphics cards (i915 it seems, in my case), access to /proc/$PID/environ to read envvars (e.g. TOR_CONTROL_PORT), access to Tor's Control Cookie file to authenticate. Strangely also /dev/dri/ to draw the UX (not covered by <abstractions/X>?) Updated with `aa-genprof`, tested under Tails 3.0.1 and Debian Stretch desktop.

The apparmor profile can be installed in `make install` by passing `DEFINES+=APPARMOR`, and optionally `APPARMORDIR=/path/`.
