fuzz: retrieve the WebAssembly spec repository in build.rs

To avoid the large download size of the spec repository mentioned
[here](https://github.com/bytecodealliance/wasmtime/pull/3124#discussion_r684605984),
this change removes it as a submodule and instead clones it shallowly
when the directory is empty (or not present) when `build.rs` is run.
