  thermald: change the default dbus policy, make it more restrictive

Status in thermald package in Ubuntu:
  Fix Released
Status in thermald source package in Trusty:
  Fix Released
Status in thermald source package in Bionic:
  Fix Committed

Bug description:
  org.freedesktop.thermald.conf default dbus policy should be more


  SRU Justification:


  With the current dbus policy one can terminate thermald using:

  dbus-send --system --dest=org.freedesktop.thermald /org/freedesktop/thermald 
  thermald can be send dbus

  ..fortunately init respawns thermald, but the policy is not
  restrictive enough, only root should be able to do this.


  This fix restricts the default policy so only root can send dbus
  messages to thermald.

  [Test Case]

  How to reproduce:

  dbus-send --system --dest=org.freedesktop.thermald /org/freedesktop/thermald 
  thermald can be send dbus

  then use: dmesg and see that init has respawned thermald (which means
  it received the dbus message and handled it)

  With the fix, the dbus-send message won't kill thermald and hence one
  won't see the re-spawn message in dmesg.

  [Regression Potential]

  Cannot think of any, low to none. Thermald is not a default install,
  it is a new packaging in Trusty and is currently op-in, so this change
  has minimal impact. Regression potential is that users won't be able
  to communicate to thermald via dbus-send, which is not the recommended
  way to shut down thermald anyhow.

  Tested today on an AMD64 trusty install.
