This changes the superproject sha variable to use the
SUPERPROJECT_REVISION as the default value if no explicit sha is
defined. Only sets up the new default if the revision value matches a
sha.
This change is required since the builder provides a revision for the
superproject that is either pinned to a sha or a branch name. If it is
pinned to a sha, we want to use this as the fallback source for
SUPERPROJECT_SHA

Android builds by default put artifacts into out/ subdirectory of
the source tree, causing the extractor to record their names as
relative. The indexer considers such files as sources, which is wrong.
Fortunately, the extractor can be fed a set of filename rewriting
rules (see build/tools/vnames.json).
Also, undo previous unsuccessful attempt use to absolute path for the
output directory to distinguish between source code and artifacts.
