make module searching even faster (in slow case) on ghc 6.10. Ignore-this: 781b093cec5f42646d48e15ba0f15e03 With ghc 6.10, the find-module command is added to ghc-pkg, which makes it much cheaper to figure out which packages provide a given module.  With this change, we first try using find-module, and if that doesn't work, we search the hard way.  A better alternative might be to check what ghc is running us to decide which to use (which would be faster on ghc 6.10 in the case where no package provides the desired module).
