Fix/prebuildify path lookup

[YOU54F]

Right two issues

1. The path lookup is looking at the root of the project folder, and not in the node_modules directory

2. env var LOG_LEVEL doesn't affect logging of the FFI native module, as that uses DEFAULT_LOG_LEVEL or the user provided instead ofcurrentLogLevel which was modified to take account of the env var LOG_LEVEL

simple test of the standalone and ffi

const pact = require('@pact-foundation/pact-core')
pact.createServer()
 .delete()
 .then(function() {
  console.log('pact ruby standalone server created and deleted')
 });

const consumerPact = pact.makeConsumerPact(
    'foo-consumer',
    'bar-provider',
    4 ,// v3 spec,
    'TRACE'
  );
const interaction = consumerPact.newInteraction('some description');

interaction.uponReceiving('a request to get a dog');
interaction.given('fido exists');
interaction.withRequest('GET', '/dogs/1234');
interaction.withResponseBody(
JSON.stringify({
    name: 'fido',
    age: 23,
    alive: true,
}),
'application/json'
);
interaction.withStatus(200);

port = consumerPact.createMockServer('127.0.0.1');
// port = consumerPact.createMockServer('localhost'); // Error in native callback - JSON.parse(ffi.pactffiMockServerMismatches(port)) 
console.log(port)
consumerPact.mockServerMatchedSuccessfully(port)
const mismatches = consumerPact.mockServerMismatches(port);
console.log(mismatches)

npm install @pact-foundation/pact-core

You can see the lookup path is /Users/yousaf.nabi/dev/fooscratch/prebuilds/darwin-arm64 but it should be ` /Users/yousaf.nabi/dev/fooscratch/node_modules/@pact-foundation/pact-core/prebuilds/darwin-arm64

      We looked for a supported build in this location /Users/yousaf.nabi/dev/fooscratch/prebuilds/darwin-arm64

      Tip: check there is a prebuild for darwin-arm64 

      check the prebuild exists at the path: /Users/yousaf.nabi/dev/fooscratch/prebuilds/darwin-arm64

      Wrong Path?: set the load path with PACT_PREBUILD_LOCATION ensuring that $PACT_NODE_NAPI_LOCATION/prebuilds/darwin-arm64 exists

      - Note: You dont need to include the prebuilds/darwin-arm64 part of the path, just the parent directory

      - Let us know: We can add more supported path lookups easily, chat to us on slack or raise an issue on github

hmm there should a third commit fixing the linting 🤔
