Andrew Brown 0c7885cc05 fuzz: improve wasm-spec-interpreter documentation, add library path (#4007)
The documentation for the `wasm-spec-interpreter` was not up-to-date,
causing some confusion on non-Ubuntu machines. This change adds the
correct dependencies to install and includes the `libgmp` path for
Fedora by default (i.e., `/lib64`).

This directory contains the necessary parts for building a library with FFI
access to the Wasm spec interpreter. Its major parts:
- `spec`: the Wasm spec code as a Git submodule (you may need to retrieve it:
`git clone -b wasmtime_fuzzing https://github.com/conrad-watt/spec`).
- `interpret.ml`: a shim layer for calling the Wasm spec code and exposing it
for FFI access
- `Makefile`: the steps for gluing these pieces together into a static library
Note: the `Makefile` must be configured with the path to `libgmp.a`; see
`LIBGMP_PATHS` in the `Makefile` (Ubuntu: `libgmp-dev`, Fedora: `gmp-static`).
