Extend Sony workaround up to and including Oreo.

Due to a platform issue the Display API couldn't report 1080p UI
and 4k SurfaceView support until Oreo. Since Oreo it is still
common for devices to misreport their display sizes via Display,
so this change switches to using system properties up to and
including Pie.

On Pie treble may prevent writing sys.display-size so check for
vendor.display-size instead.
