ar71xx: WNDR3700: enable RFKILL function for Wifi button

Wifi button for WNDR3700 dual band routers has been renamed to "rfkill"
and its emitted keycode changed to KEY_RFKILL. This allows OpenWrt/LEDE
to support it 'out of the box' without additional tweaking.

Until this patch, button had been sending BTN_2 keycode which was
ignored by default (no action script present). To get expected behaviour
of switching radios on and off, user had to manually rename/link
'rfkill' script to name 'BTN_2' in /etc/rc.button directory.

This patch follows similar changes for other Netgear ar71xx routers,
for example WNR2000v3. It applies cleanly to both latest trunk and 17.01
branch. Tested on WNDR3700v1.
