 Hadrian: install patches 'haddock-{html,interface}'

 Since the `$(docdir)` can be picked independently from the `$(libdir)`,
 we need to make sure that that the `haddock-html` and `haddock-interface`
 fields in the package DB (which is in the `$(libdir)`) get updated to
 point to the appropriate places in the `$(docdir)`.

 NB: in the make system, `ghc-cabal` would cover this sort of thing by
 re-running `configure` on installation, but here we get away with a
 couple lines of `sed` and a call to `ghc-pkg recache`.

 Fixes #16202.
