packagegroup-base: pull in iw as well as wireless-tools

As was discussed in the commit which adds iw:

iw uses cfg80211/nl80211, which is the way of the future. wireless-tools uses
WEXT, which uses ioctl, which is in deep maintenance mode. See
http://wireless.kernel.org/en/developers/Documentation/Wireless-Extensions.
Also https://wireless.wiki.kernel.org/en/users/Documentation/iw indicates "The
old tool iwconfing, which uses Wireless Extensions interface, is deprecated
and it's strongly recommended to switch to iw and nl80211."

wireless-tools is kept as well for now for compatibility reasons, until we
have verified that all the network configuration mechanisms are using iw.

This adds VIRTUAL-RUNTIME_wireless-tools as a distro convenience.
