parentcommit-graph.c: ensure graph layers respect core.sharedRepository (diff)

commit-graph.c: make 'commit-graph-chain's read-only
In a previous commit, we made incremental graph layers read-only by using 'git_mkstemp_mode' with permissions '0444'. There is no reason that 'commit-graph-chain's should be modifiable by the user, since they are generated at a temporary location and then atomically renamed into place. To ensure that these files are read-only, too, use 'hold_lock_file_for_update_mode' with the same read-only permission bits, and let the umask and 'adjust_shared_perm' take care of the rest.
