Build in stages to shed 9gb from the jvm base builder image (#12649) 

This PR reduces the final `base-builder-jvm` image by 9GB.

Careful review and full integration testing across oss-fuzz projects are
required before merging, obviously.

This worked on two projects I was interested in. One that used
`@FuzzTest` and one that used `fuzzerTestOneInput`
