Bug description:
  Snaps that use the app indicator area via Qt can't display their icon
  there.

  Steps to reproduce and screenshot:
  https://github.com/nuttyartist/notes/pull/77

  Some research:

  - Uses http://doc.qt.io/qt-5/qsystemtrayicon.html
  - The indicator icon is created under /tmp under a randomly generated directory name

  didrocks mentions also:

  1. The application says "this is my menu, and here is my icon at that address", the address being /tmp/blablabla
  2. appindicator receives the bus messages
  3. and says "let's have a look at this icon at that address"
  4. BUT! /tmp in the snap is different form system /tmp

  ====================================================================================

  SRU bug for libappindicator:

  [Impact]

  Indicator icons pointing to a position inside the snap aren't properly
  found by unity, that shows a "missing icon" emblem

  [Test case]

  * Download this yaml file http://pastebin.com/raw/FpEvQYGN and save it as snapcraft.yaml
    in any folder you want
  * Run:
    - snapcraft prime
    - sudo snap try prime
    - snap run gtk3-appindicator

  An indicator should open (with proper icon), then if you select "Set
  icon with Full Path" and/or "Enable Local Theme" from its menu, you
  should see a proper icon.

  When snaps are generated in non updated systems, the icon will be
  still missing.

  [Regression potential]

  If $SNAP is defined for an app not running in snap confinement the
  icons couldn't be properly visible
