[PATCH] D-Bus: Add 'wep_disabled' capability

Since commit 200c7693c9a1 ('Make WEP functionality an optional build
parameter'), WEP support is optional and, indeed, off by default.

The distributions are now catching up and disabling WEP in their builds.
Unfortunately, there's no indication prior to an attempt to connect to a
WEP network that it's not going to work. Add a capability to communicate

Unlike other capabilities, this one is negative. That is, it indicates
lack of a WEP support as opposed to its presence. This is necessary
because historically there has been no capability to indicate presence
of WEP support and therefore NetworkManager (and probably others) just
assumes it's there.
