Use an option rom instead of boot sector for -kernel
Generate an option rom instead of using a hijacked boot sector for kernel booting. This just requires adding a small option ROM header and a few more instructions to the boot sector to take over the int19 vector and run our boot code. A disk is no longer needed when using -kernel on x86.
