xkb: Add missing 'supported' field to GetNamedIndicator reply
The protocol encoding has it:
http://www.x.org/releases/current/doc/kbproto/xkbproto.html#appD::Requests
1 CARD8 opcode
1 15 xkb-opcode
[...]
1 1 Reply
1 CARD8 deviceID
2 CARD16 sequence number
[...]
4 SETofKB_BOOLCTRL map.ctrls
1 BOOL supported
3 unused
And xkbGetNamedIndicatorReply in XKBproto.h also.
Finally, the server does send it, though it's always TRUE.
