[PATCH] kdumpgui: Allow accessing and creating the libblkid cache

+++ This bug was initially created as a clone of Bug #1022762 +++

Apart from the systemd shortcoming that's being addressed in the above bug, I believe there still are two changes needed to the policy.

Please have a look at attached patch files, they contain explanations in their headers.

The denials:

Systemd log for "systemctl enable kdump.service" and "systemctl disable kdump.service" (from an unconfined shell session):

[PATCH] systemd: Allow systemctl users to reload systemd state
Comment 2 Lubomir Rintel 2013-12-28 10:21:26 UTC 
Ping?

The enable/disable access vectors have been fixed in upstream systemd Git now.
What about the additional two patches needed to make s-c-k works that are attached here; do those make sense?
