We automatically convert that to use sys.executable now which is
always available on all platforms (because we're running with it).
On some platforms like NetBSD, `python` doesn't exist, and you must
use a specific python version. On most other distros, `python` is
Python 2, and we don't want to depend on that.

All these scripts were being used as `find_program()`, so we do not
lose any test coverage by doing this.
On some distros, running this causes Python to find the file itself as
the implementation of the `copy` module:
$ python3 copy.py
