Merge bitcoin/bitcoin#23585: scripted-diff: Drop Darwin version for better maintainability

2f356a0 scripted-diff: Drop Darwin version for better maintainability (Hennadii Stepanov)

Pull request description:

  After this PR, any macOS tools version bumping in the future will touch fewer files in the repo.

  Pointing a Darwin version for the `--host` system does not matter for the following reasons:

  - in terms of the resulted binaries, we should only care about the minimum supported macOS version which is a separated parameter in our build system.

  - in terms of the build system itself, the usage of the `$(host)` variable is self-consistent enough. Btw `$(host_os)` value already has the version dropped:
  ```
  $ make -C depends --no-print-directory print-host_os HOST=x86_64-apple-darwin19
  host_os=darwin
  ```
