v4l2object: Add function to get crop regions from device

Get the current crop bounding region from the V4L2 device so
that it can be provided to applications and used to validate
crop settings. Also make the default crop region available so
that it can be used to reset the crop when appropriate.

Uses the selection API when available with fallback to the crop
API for older kernels.
