[patch-project] Set CLI to executable on build for consistency with y…

…arn in root (#27687)

# Why

- I noticed that the working tree was dirty when trying to run this job:
https://github.com/expo/expo/actions/runs/8287945362/job/22681450966
- I saw when I ran `yarn` locally in the root of the repo (by chance, I
happened to do it with a clean slate / no node_modules) it modified
build/cli/index.js to add +x to mode.
- I figured this would be fine to commit and solve all of our problems.
But then check-packages failed:
https://github.com/expo/expo/actions/runs/8289007758/job/22684616383

So:

### 1. after running yarn clean && yarn build in patch-project

```
ls -l build/cli/index.js
-rw-r--r--@ 1 brent  staff  4002 14 Mar 17:49 build/cli/index.js
```

### 2. after running yarn from root (with a clean node_modules):

```
ls -l build/cli/index.js
-rwxr-xr-x@ 1 brent  staff  4002 14 Mar 17:49 build/cli/index.js
```

I believe this happens because `yarn` will link all workspace `bin`s and
ensure they are executable. When we use `expo-module clean` we delete
the build directory and re-generate it, re-creating it without
executable mode. This is usually fine because in other pkgs we don't
keep the bin inside of src, but in this case..

# How

Add `chmod +x` in build script 

# Test Plan

- patch-package and iOS Client - EAS workflows should both work.
([confirmed iOS client
here](https://github.com/expo/expo/actions/runs/8289875387/job/22687033418))
- The two scenarios I shared in the "Why" section both produce the same
results
