Remove redundant .hi-boot files. The earliest compiler we claim to be able to compile GHC with is GHC 5, and that needs hi-boot-5 boot files. So the plain hi-boot files are dead. Reason for removing them now is that my big commit accidentally splatted them with binary data; so if you ever want to recover them, go back one revision beore the one I'm deleting.
