Drop the patch for making WASI reproducible
We found that wasi-libc wasn't reproducible (#40750 (closed)), so we fixed upstream, and then backported. The reason is that we use the same version of the wasi-sysroot (actually, wasi-sdk) as Firefox.
So, when both the upstream projects update, we will be able to drop our patch, since it will be already integrated.
The WASI-SDK currently has a pre-release to enable threads support. Maybe they'll bump the wasi-libc again, since it contains another PR about threads, that the pre-release doesn't have.
We have a couple of months before 115 goes to nightly. So, tentatively adding the ESR115 label here.
