Subject: [PATCH] Include sanitize blacklist and other extra deps as part of
 scan-deps output

Summary:
Clang's -M mode includes these extra dependencies in its output and clang-scan-deps
should have equivalent behavior, so adding these extradeps to output just like
how its being done for ".d" file generation mode.
