Bump submodules of hpc and hpc-bin to version 0.7.0.0

We had some problems with SafeHaskell and the declared bounds of the hpc package here: hpc/hpc#10 (closed)

The problem was that the directory package lost its InferredSafe property and hpc modules which imported modules from the directory package were declared Safe. In version hpc 0.7.0.0 all promises about SafeHaskell were dropped, and the util hpc-bin was also updated to allow version 0.7.0.0. This version has also already been released on Hackage: https://hackage.haskell.org/package/hpc
