tuned-ppd: Support the new UPower PPD namespace

Since version 0.20, power-profiles-daemon exposes its DBus interface under "org.freedesktop.UPower.PowerProfiles" alongside the previous name. To be compatible with PPD, this commit implements the same change into tuned-ppd. Resolves: redhat-performance#683
