CarpetX does not update cctk_iteration and cctk_time in cached per-block GHs

[Roland Haas]

In git hash 13978ac "CarpetX: Cache cctkGH data structures instead of modifying them" of cactusamrex CarpetX started to create one copy of cctkGH for each block.

However those cctkGH are never updated eg for current time or iteration resulting in cctk_iteration seen be scheduled functions to be 0 all the time.

Pull request https://bitbucket.org/eschnett/cactusamrex/pull-requests/14/carpetx-update-time-and-iteration-in-block attempts to ameliorate this by updating cctk_iteration and cctk_time of all block GHs in the CyleTimelevels routine.
