Python package generation generates invalid rpm specfile when there are files in the filename
### Describe the bug

The `briefcase package` command fails with messages such as:

```
error: File must begin with "/": manifest.xml
error: File must begin with "/": (dev).tmpl

```

Lines matching the strings listed in the spec file contain a space character:

```
/usr/lib64/rpmtest/app_packages/setuptools/command/launcher manifest.xml
/usr/lib64/rpmtest/app_packages/setuptools/script (dev).tmpl

```


### Steps to reproduce

In a Linux environment (reproduced on Almalinux 9)
1. Create a new project with `briefcase new`
2. Add `redislite` to the [tool.briefcase.app.rpmtest] requires
3. Create the Application using `briefcase create`
4. Build the project using `briefcase build`
5. Attempt to create an rpm package using `briefcase package`

### Expected behavior

An rpm package gets created
