build: remove iwinfo dependency

build: remove iwinfo dependency

Do not always try to include iwinfo in the images when wpa supplicant or
Broadcom nas is also included. iwinfo is incompatible with current
default configuration.

iwinfo is only build when CONFIG_WIFI_SCRIPTS_UCODE is not set. If
CONFIG_WIFI_SCRIPTS_UCODE is not set kmod-cfg80211 depends on iwinfo,
so it should be included in all images with wifi drivers.

The CONFIG_WIFI_SCRIPTS_UCODE option was recently changed to be active
by default.

This should fix the current buildbot build failures.

This reverts commit 6435b8bb27ea ("build: include iwinfo by default
if nas or wpad(-mini) is selected")

Fixes: 04e9929c47e9 ("wifi-scripts: enable ucode scripts by default")
