cache: use const char * for get_object_directory()

Browse source 
The get_object_directory() method returns the exact string stored at
the_repository->objects->odb->path. The return type of "char *" implies
that the caller must keep track of the buffer and free() it when
complete. This causes significant problems later when the ODB is
accessed.

Use "const char *" as the return type to avoid this confusion. There are
no current callers that care about the non-const definition.
