ext/objspace/objspace_dump.c: print addresses consistently
The format addresses are printed in are different if you use `ObjectSpace.dump_all(output: :stdout)` vs. `ObjectSpace.dump_all(output: :string)` (or `ObjectSpace.dump`) due to differences in the underlying `vfprintf` implementation. Use `"%#"PRIxVALUE` to format `VALUE`. Co-authored-by: Ashe Connor <ashe@kivikakk.ee> git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64974 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
