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.
