- Add pkg rules to the search, specifically so that we can pull the full release tar instead of the busybox binary. - Shift the tree_sitter exclusion to the script, so that it's easier to use the script. - tcmalloc_if_linux_opt isn't really interesting (it's referenced by .bazelrc). - Misc tiny changes to the query, just to simplify it.
