Brew upgrade leads to confusing hhvm state

Yeah, there's a bunch of metadata, we can't just re-use the existing build artifact

[jjergus]

This sounds reasonable to me and probably a simple change (possibly just change ln -sf ... to cp ... in the build script?) but I don't know a lot about Homebrew, @fredemmott what do you think?

[fredemmott]

This is a good change; I didn't think it was that trivial because of $problems_we've_already_solved_to_make_the_symlink_updating_working

[fredemmott]

oh, this might need a rebuild actually - the package name is part of the binary package filename
