MAINTAINERS: consistently exclude wireless files from NETWORKING [GENERAL]

We already exclude wireless drivers from the netdev@ traffic, to
delegate it to linux-wireless@, and avoid overwhelming netdev@.

Many of the following wireless-related sections MAINTAINERS
are already not included in the NETWORKING [GENERAL] section.
For consistency, exclude those that are.

* 802.11 (including CFG80211/NL80211)
* MAC80211
* RFKILL
