Kconfig: Expose net/sock/util configurations

[leandrolanzieri]

Contribution description

This PR moves configuration macros of SOCK utilities module to the CONFIG_ namespace. It also exposes them to Kconfig.

Testing procedure

You can check the values in some application that uses this module (e.g. examples/gcoap). Make sure configurations take the default values as usual from the header files. Run make menuconfig, enable the configuration of the module and change the values.

You can use this patch:

Run make menuconfig, enable the configuration of the module and change the values.

@leandrolanzieri I haven't used kconfig much yet, how do I enable it for the module? :)

In an application that uses the module (e.g. examples/gcoap) you can run make menuconfig, there navigate to System > Networking and enable the option Configure SOCK utility functions with space or enter keys. You can also get into that submenu and change parameters. Save with S and try to build.

I had done that but didn't specify the BOARD when reunning menuconfig, which is why I didn't see the changes at first, may bad, works as expected.
