ACPI: Execute _PTS before system reboot

All kernels from 4.8.0 are affected at the moment. A special thanks to Giampaolo on kbz for bisecting sources down to the root cause. An rpmbuild compatible patch and an updated spec file are provided for reverting this commit. Binary RPMs for F24 and F25 are available at https://daniele.vigano.me/files/5e366c91-41ac-4e43-be8e-15139c0463b1/
