igt/gem_stolen: Check for available stolen memory size

Check for available stolen memory size before attempting to run
the stolen memory tests. This way we make sure that we do not
create objects from stolen memory without knowing the available size.

This checks if the kernel supports creation of stolen backed objects
before doing any operation on stolen backed objects.

Also correcting the CREATE_VERSION ioctl number in getparam ioctl,
due to kernel changes added in between.

v2: Removed size argument for checking stolen memory availability (Tvrtko)
