Drop the pm-utils depdency.

[packaging] Drop pm-utils dependency.

Dropping pm-utils dependency as it has not been used since upower
0.9.20. Also obsoleting the old pm-utils version to get it removed from
old images. Also fixed some configure options that have changed since
the packaging was originally done.

Is there is a danger if there will be some package depending on pm-utils this "Obsoletes" prevents pm-utils from beeing installed?
There should some kind of autoclean/remove to handle removal of packages installed by deps and not needed anymore.
