RFR: 8289755: Remove --enable-reproducible-build from jib profile

Tue Jul 5 16:09:43 UTC 2022

Since [JDK-8288396](https://bugs.openjdk.org/browse/JDK-8288396), the flag ` --enable-reproducible-build` is deprecated, and does nothing but print a warning. It is still included in the jib profiles, which make they output a warning.
