Sandbox: Fix loop in CollectMatches() (#1412)

The `CollectMatches()` function uses the `yr_rule_metas_foreach()`
macro iterate over the rule metadata. The macro expands to a for-loop
that already increments the loop variable, so we should not do this
again.

Drive-by:
- Run Buildifier on `bazel/yara_deps.bzl`, deleting a few empty lines
