Debugging issues on the build servers can be difficult because the intermediate files are not visible. Gzip ninja file and Makefiles generated by Soong and the ninja files generated by Kati to the dist directory, and also copy all of the finder output files. Bug: 157656545 Test: m dist nothing Change-Id: I48d75305e551ccae81c7a55721981cf58acd838b
