* Tidy and trim the type environment in mkBootModDetails
Should fix Trac #1833
We were failing to trim the type envt in mkBootModDetails, so several
functions all called (*), for example, were getting into the interface.
Result chaos. It only actually bites when we do the retyping-loop thing,
which is why it's gone so long without a fix.
