Subject: [PATCH] chore: fix output_package unbound variable in GNU/Linux
 (#767)

The `$output_package` variable is defined inside the `package_x$ARCH`
functions, which means that if we run the following commands:

```sh
./scripts/build/linux.sh package x64
./scripts/build/linux.sh appimage x64
```

The `$output_package` variable will not be defined when the script runs
the `appimage` command.

To workaround this issue, we declare a new `$package_directory` variable
inside the `appimage` command clause.
