[BUG] build_editable does not emit #!python shebang for scripts

Description

Assume a script like this

#!/usr/bin/env python3
from pkga import main

main()

and a setup.py like this

setup(
    name="pkga",
    scripts=["scripts/pkga-script"]
)

When running build_editable on such a project, the file pkga-0.1.0.data/scripts/pkga-script in the editable wheel produced has the path to the python interpreter used for the build.

This is unexpected. When running build_wheel, the shebang is #!python.

Note that script entry points correctly emit #!python both for regular and editable wheels.

Expected behavior

The shebang in the script in the editable wheel should be #!python too.

How to Reproduce

I don't have packaged the repro in a self-contained repo, but the example above should be explicit enough. Let me know if you need more information to reproduce.

I pushed a commit and started on a PR before I realized the relevant logic is found in distutils.
