Bug description:
  upstart in user session manages environmental variables and most
  things have them, however Alt-f2 started processes lack them.

  [Impact]
  Some environment variables are missing from apps that are launcher from Alt+f2 command lens, or in general with dbus-activation (an example might be gnome-terminal, global menu not working).

  [Test case]
  Super Key -> "xterm" -> Enter -> env | grep SSH

  it should return something like:
  SSH_AUTH_SOCK=/run/user/$UID/keyring-<random-stuff>/ssh

  Alt+F2 -> "xterm" -> Enter -> env | grep SSH

  The returned values should match the results got from the xterm
  instance that has been ran from unity dash application lens (the one
  opened with Super).

  The same should be checked for the variable XDG_MENU_PREFIX

  Before this fix happened we had this result:
    via Super Key -> the environment is correct
    via Alt-F2 -> it is not

  [Regression potential]

  Nothing known. Some variables could be overridden, but this is
  expected.
