tests/cdrom-test: Test booting from CD-ROM ISO image file 

We already have the code for a boot file in tests/boot-sector.c,
so if the genisoimage program is available, we can easily create
a bootable CD ISO image that we can use for testing whether our
CD-ROM emulation and the BIOS CD-ROM boot works correctly.
