RFR: 8341735: Rewrite the build/AbsPathsInImage.java test to not load the entire file at once [v7]

[Daniel Hu]

> These changes should prevent entire binary files from being loaded into memory for build/AbsPathsInImage.java test. I chose a default buffer size of 8KB since BufferedInputStream uses that, but open to alternative solutions. GHA passes and test passes on linux x64.
