`s3ForcePathStyle` works for publishing but not installation

[jared-duo]

I am using LocalStack for a local S3 for verification, integration tests etc., so I am using localhost and other domains not part of the normal production AWS forms.

I have followed the configuration instructions here and publishing works perfectly, but the hosted_path property in the lib/utils/versioning.js doesn't take this parameter into account (we can see in the PR that introduces the s3ForcePathStyle parameter that the evaluate method in versioning.js accepts the parameter, but never uses it.)

I believe the opts.hosted_path needs to be altered to account for the bucket name being part of the path so that installation may also occur from a non-standard AWS path.

Example:

Given a

package.json

{
  ...
    "binary": {
    "module_name": "my-module",
    "module_path": "<some_path>",
    "remote_path": "/npm/{module_name}/addon/",
    "package_name": "{module_name}.tar.gz",
    "host": "https://localhost.localstack.cloud:4566",
    "region": "us-east-1",
    "bucket": "my-packages",
    "s3ForcePathStyle": true
  }
 ...
}

and an S3 bucket available at https://localhost.localstack.cloud:4566/my-packages an invocation of node-pre-gyp publish will place the tarball correctly in https://localhost.localstack.cloud:4566/my-packages/npm/my-module/addon/my-module.tar.gz, but an invocation of node-pre-gyp install will try to download the tarball from https://localhost.localstack.cloud:4566/npm/my-module/addon/my-module.tar.gz - notably without the bucket in the path.
