0dade9154d2e5d4b1725fbe27720d54396c4db1d fuzz: remove no-longer-necessary packages from fuzzbuzz config (fanquake)
Pull request description:
I take it this is actively being used, given [comments in #20560](https://github.com/bitcoin/bitcoin/pull/20560#issuecomment-743747317); so remove old dependencies from setup.

Pull request description:
Add fuzzbuzz integration.
Just like #15338 enabled optional FreeBSD building via Cirrus CI (`.cirrus.yml`) this PR adds optional fuzzing via fuzzbuzz (`.fuzzbuzz.yml`).
Having this merged makes is easier for people to fuzz Bitcoin Core (via their forked repos) using their fuzzbuzz account and then hopefully submit coverage increasing corpus additions upstreams to to https://github.com/bitcoin-core/qa-assets.
Historically it has been mostly been me and MarcoFalke who submit test cases to `qa-assets`, but with this change hopefully more people will join the hunt for coverage increasing fuzzing inputs :)
