modules: hostap: Add a config option for WPA control timeout

WPA control interface timeout is hardcoded to 10s, add a configuration
option to remove the hardcode, this is needed sometimes as a workaround
e.g., crypto taking too long to complete the request.

Work around for #79834, increase the default from 10 to 15s, in positive
case this will have no impact.
