using directory for actions output causes issue like crbug.com/1315457 ninja explain: output obj/third_party/dawn/src/tint/fuzzers/tint_generate_wgsl_corpus.stamp older than most recent input gen/third_party/dawn/src/tint/fuzzers/fuzzer_corpus_wgsl (1649712735 vs 1649712999) Use stamp file instead of directory.
