Boot-generated uberjar zip file has corrupted content on Java 13

**Describe the bug**
The JAR file produced by `boot build` when used in the default way produces a zip containing a corrupt metadata file (`META-INF/MANIFEST.MF`)

**To Reproduce**
Steps to reproduce the behavior:
1. Create a new boot project
```
boot -d boot/new new -t app -n myapp
cd myapp
boot run
```

2. Run `boot build` to generate a jar

3. Use `unzip` command to unzip the jar
`unzip target/myapp-0.1.0-SNAPSHOT-standalone.jar`

**Expected behavior**
The jar file should `unzip` without error.

**Actual**
The JAR fails to unzip on this file:
```
inflating: META-INF/MANIFEST.MF bad CRC bd07333f (should be 5fbe64cb)
```

**Desktop (please complete the following information):**
- OS: Mac OS X 10.14.6
- BOOT_VERSION=2.8.3
- BOOT_CLOJURE_VERSION=1.10.1
- BOOT_CLOJURE_NAME=org.clojure/clojure
- JDK 13 build 33 (2019/8/9)

**Additional context**
- The JAR does run without issue using `java -jar target/my-app.jar`
- Ran into this issue when deploying an app to Elastic Beanstalk, which unzips the jar using the `unzip` command
- Reproduced the issue locally with my own app, and then with a brand new app using the instructions above.
- After downgrading to JDK 1.8, it works.
- Have not tested the JDK versions in between 13 and 1.8 (11, 12)
