[Buildroot] [PATCH 1/2] package/wpa_supplicant: add Config.in option for WPA3

[Sergey Matyukevich <geomatsi@gmail.com>]

New wpa_supplicant v2.9 enables by default WPA3 features such as
SAE and DPP. Building those features requires openssl.

This patch adds Config.in option for WPA3 support in wpa_supplicant.
When this option is selected, libopenssl is also selected and WPA3
features OWE, SAE, DPP are enabled in wpa_supplicant configuration.
When this option is deselected, then all the above WPA3 options
are disabled.
