Merge bitcoin#18556: build: Drop make dist in gitian builds

2aa48ed refactor: Drop unused ${WRAP_DIR}/${HOST} directory (Hennadii Stepanov)
1362be0 build: Drop make dist in gitian builds (Hennadii Stepanov)

Pull request description:

  After the merge of bitcoin#18331, the packaged source tarball is created by `git archive`, but the binaries are built from another one which is made by `make dist`.

  With this PR the only source tarball, created by `git archive`, is used both for binaries building and for packaging to users.

  Close bitcoin#16588.
  Close bitcoin#18547.

  As a good side-effect, bitcoin#18349 becomes redundant.

  **Change in behavior**

  The following variables https://github.com/bitcoin/bitcoin/blob/1b151e3ffce7c1a2ee46bf280cc1d96775d1f91e/configure.ac#L2-L6

  are no longer used for naming of directories and tarballs.

  Instead of them the gitian descriptors use a git tag (if available) or a commit hash.

  Also a small refactor commit picked from bitcoin#18404.

    ACK 2aa48ed - I've had a quick look over this, and don't want to block merging if this actually gets as closer to finally having this all sorted out. Obviously we've still got bitcoin#18741, and after speaking to Carl this morning, there will likely be even more changes after that (not Guix specific).
