This resets all timestamps present in jars produced by kotlinc.
This is important for build systems like bazel that rely on
deterministic outputs.
Before:
```
$ kotlinc ~/test.kt -d /tmp/a.jar
$ kotlinc ~/test.kt -d /tmp/b.jar
9ab80cd40c9293a7a66adf1154d4e6e9aa92d5b0 /tmp/a.jar
1ba022697317f796bd123fb4dc95418a18bcb51a /tmp/a.jar
6d2a2683470c24928f3fbd6768a4c57f55b0d196 /tmp/b.jar
$ unzip -l /tmp/a.jar
Archive: /tmp/a.jar

After:
```
$ kotlinc ~/test.kt -d /tmp/a.jar
$ kotlinc ~/test.kt -d /tmp/b.jar
$ shasum /tmp/a.jar /tmp/b.jar
