sparse: Rename the file and header
The Android sparse image format is currently supported through a file called aboot, which isn't really such a great name, since the sparse image format is only used for transferring data with fastboot. Rename the file and header to a file called "sparse", which also makes it consistent with the header defining the image structures.
