Use bytesize instead of length to determine Content-Length

[KidkArolis]

If body_json is a string that contains £ symbol, Content-Length header will be set incorrectly by HTTParty. See https://github.com/typhoeus/typhoeus, they handle that correctly.

response = HTTParty.post(endpoint,
  :headers => {
    'Content-Type' => 'application/json; charset=UTF-8'
  },
  :body => body_json
)

Any concerns about backwards compatibility for a change like this? Also, a pull request would certainly help.

Would this lead to EOF when sending to an webserver?

Pretty sure, back in the time, it was a problem with Net/HTTP in ruby 1.9.3. Since 2.0 bytesize is used to determine set Content-Length
