Enable EFIv1 compression in bmpbklk_utility.

This lets bmpbklk_utility generate BMPBLOCKs with EFIv1-compressed bitmaps.
It also adds the ability to display or unpack BMPBLOCK blobs.

The compression/decompression routines come from the tianocore EDK on
sourceforge and are written in C, so now there's a mix of C and C++, but it
works just fine.
