Prepare multiproduct_kati to run on the build servers

Adds a -dist argument that will use DIST_DIR to save logs.

Also writes a summary of each std.log to stderr on errors, so that the
error is more likely to show up in the error reporting. This output is
prefixed with "> " to differentiate it from the progress reports from
multiproduct_kati itself.

Test: multiproduct_kati -only-config
Test: DIST_DIR=dist build/soong/build_test.bash -dist (introducing errors)
