Update process submodule

This is needed to prepare for #11026 as this update
relaxes the upper bounds on `base` to allow for `base-4.9.0.0`

This also needs to relax a few upper bounds on process in some cabal files

(there will be another process submodule update soon, as a major
version bump of process' version is still pending)
