macayu17 6188e9efa9 pyenv-binary: add the generate-installer subcommand
* Relocation only implemented for Linux (requires patchelf + ldconfig -p)
* Shell-completing file name is not possible with current Pyenv completion logic:
  `pyenv-complete` does not pass info about the word being completed
* Fix `save`-produced tarball to be compatible with Python-Build fetch_tarball()
* Reuse test_helper from core
