The previous `cargo install cargo-fuzz --locked` resolved against
cargo-fuzz's own Cargo.lock which pins to rustix 0.36.5. That rustix
version still annotates its source with internal #[rustc_*] attributes,
and the current nightly compiler rejects those attributes from
out-of-tree crates, so cargo-fuzz never finished compiling on CI:
error: attributes starting with `rustc` are reserved for use by the
`rustc` compiler
--> rustix-0.36.5/src/backend/linux_raw/io/errno.rs:28
error: could not compile `rustix` (lib) due to 4 previous errors
error: failed to compile `cargo-fuzz v0.13.1`
Switch the install to taiki-e/install-action, the same prebuilt-binary
provider we already use for cargo-llvm-cov. That skips the full
transitive-dependency compile and lets the fuzz-smoke job actually run.
