Unix sockets don't support "body"

[OmgImAlexis]

Describe the bug

• Node.js version: v13.12.0
• OS & version: Unraid beta 8

Actual behavior

 GotError: The "source" argument must be of type function or an instance of Stream, Iterable, or AsyncIterable. Received undefined
    at onError (/usr/local/node/graphql-api/node_modules/got/dist/source/request-as-event-emitter.js:140:29)

  name: 'RequestError',
  code: 'ERR_INVALID_ARG_TYPE'
}

When trying this against any HTTP endpoint the request works as expected.

Expected behavior

No error and the request to finish.

Code to reproduce

Removing the body options stops the error being thrown.

import got from 'got';
got.post('unix:/var/run/graphql-api.sock:/graphql', {
    headers: {
        'x-api-key': 'test123'
    },
    body: 'this is the body'
}).then(console.info).catch(console.error);

Checklist

• [x] I have read the documentation.
• [x] I have tried my code with the latest version of Node.js and Got.

This works with requests for example.

const request = require('request');

request.post('http://unix:/var/run/graphql-api.sock:/graphql', {
    headers: {
        'x-api-key': 'test123'
    },
    body: 'this is the body'
}, (error, response) => {
    if (error) {
        console.error(error);
    }
    console.info(response);
});
