test(util): update exclude glob to data/*.log for slash-aware matching

Bare `*.log` no longer crosses `/` after #1732, so the exclude glob in
the search_files parametrization is anchored to data/ to keep excluding
data/b.log. Matches the repo convention that `**` is required to cross
directory boundaries (see test_search_files_glob_patterns).
