Merge bitcoin#29733: build, macos: Drop unused osx_volname target

eff19fa build, macos: Drop unused `osx_volname` target (Hennadii Stepanov)

Pull request description:

  The `osx_volname` makefile target was introduced in bitcoin#7192 and was used to pass the package name to Gitian scripts as a content of the `osx_volname` file.

  With the current Guix scripts, the `osx_volname` file is never read. Therefore, its creation might be omitted.

  My Guix builds:
