cleanup(stable): use wasm-strip on extism-runtime.wasm (#467)

There were some scenarios where the kernel was not allocating enough
pages to get data back into the plugin. So some host functions were
failing when the output was right on this boundary.

We will come back with tests and cherry pick this over to main. For now
we want to get out a 0.5.1 fix
