Creating a venv with `python3 -m venv foo` and then reinitializing it with `python3 -m venv foo` fails with a `Error: [Errno 13] Permission denied: '/path/to/cwd/foo/bin/activate.fish'` with the CPython interpreters from Nixpkgs.

The method `EnvBuilder.install_scripts` that is responsible for copying the files, copies the permissions, instead of explicitly stating what permissions are needed. This fails with the Nixpkgs builds of CPython because in Nixpkgs the entire store is made read-only.

Files that need to be copied from the installation during run-time should be explicit about the permissions they require, instead of depending on their current permissions.
