Previously we used consolehelper in order to authenticate user who wants to run
mtr-gtk. In Fedora we have newer framework providing access control for
privileged operations, policykit.
This commit replaces consolehelper configuration and provides policy file for
policykit and shell wrapper which runs mtr via pkexec. Note that this is not ideal and
we haven't gained a lot by this.
In the long run we should really decouple gtk frontend and mtr backend. Backend
then would have CAP_NET_RAW capability encoded in filesystem and as soon as
possible it would drop that capability and start providing data to be rendered
by gtk frontend which would run completely unprivileged.

We have to make sure that it is obvious how one can create tarball
included in srpm if it doesn't originate upstream.
generate-tarball.sh will create xz compressed tarball which doesn't
include any object files. This script will be dropped as soon as
creation of upstream tarball works properly again.
