In a recent CL I moved the corpus of the wasm fuzzer and of the
wasm-asmjs fuzzer to a different directory
(wasm_corpus and wasm_asmjs_corpus) so that the corpus is not executed
on the try-bots. With this CL I remove the old corpus from the
.gitignore file.

In addition I removed the hooks for wasm_corpus and
wasm_asmjs_corpus from the V8 DEPS file, because in a V8 checkout
they are not used anyway.

I also added code to the test runner to delete all *.wasm files
from the directories test/fuzzer/wasm and test/fuzzer/wasm_asmjs.
This code should be removed in a week, but it will help my coworkers
to cleanup their V8 checkout.

This adds:
* A script (tools/update-wasm-fuzzers.sh), which creates a new fuzzing seed
  corpus and uploads to google storage (you must have the right credentials).
* A new pair of DEPS entries to pull in the current version of the corpus
  based on a checked in pair of hash files.
