Merge #17057: build: switch to upstream libdmg-hfsplus

9192ce5d634f4c65776d14539e9663c67b4367d3 depends: pull upstream libdmg-hfsplus changes (fanquake)
9b54f3436bb9a2d23bd84c0da99168386e2d5c31 depends: latest config.guess & config.sub (fanquake)

Pull request description:

  Pulled the first two commits off #16392, as they are standalone.

  Corys PRs (https://github.com/planetbeing/libdmg-hfsplus/pull/7, https://github.com/planetbeing/libdmg-hfsplus/pull/8) have been merged, and the author was active for a little while in 2017/18, so switch back to the upstream [`libdmg-hfsplus`](https://github.com/planetbeing/libdmg-hfsplus) repo. I've added the last of Corys patches into depends.

  [Switching back to upstream discussion](https://github.com/bitcoin/bitcoin/pull/16392#discussion_r303610767).

Top commit has no ACKs.
