target.mk: enable iwinfo by default with any wpad variant

There are currently several variants of 'wpad' package but the 'iwinfo'
is included by default only if 'wpad', 'wpad-{basic*,mini}' or 'nas'
packages are included in {DEVICE,DEFAULT}_PACKAGES. Use 'wpad-*'
pattern to include 'iwinfo' with any 'wpad' variant.
