net, net-lwip: wget: suppress console output when called by EFI

Browse Source 
Functions called from EFI applications should not do console output.
Refactor the wget code to implement this requirement. The wget_http_info
struct is used to hold the boolean that signifies whether the output is
allowed or not.
