This implements a passthrough disk driver that translates the read/write block addresses by a fixed offset. This could form the basis of MBR partition support if we were to parse the MBR table at boot and create that OffsetDiskDevice dynamically, rather than seeking to a fixed offset. This also introduces a dependency in the form of grub. You'll need to have 32-bit grub binaries installed to build the project now. As a bonus, divorcing Serenity from qemu's kernel loading means we can now *technically* boot on real hardware. It just... doesn't get very far yet. If you write the `_disk_image` file to an IDE hard drive and boot it in a machine that supports all the basic PC hardware, it *will* start loading the kernel.
