fix(http_server): Simple http server socket len fix

Browse Source 
The socket address length is not typecasted properly while
passing to bind and sendto functions. Due to this
http_server/simple was not running with target linux on MacOS
used to give error -

I (132253266) port: Starting scheduler.
I (132253269) esp_netif_loopback: loopback initialization
I (132253269) example: Starting server on port: '8001'
E (132253270) httpd: httpd_server_init: error in creating ctrl socket (22)
I (132253270) example: Error starting server!

With this commit, simple http server runs with target linux
on MacOS for IPV4 configurations
