FT: Fix RRB for FT over-the-air case

Commit 66d464067d626cc64c5a543a8f91fe58727f4e5e ('FT: Register RRB
l2_packet only if FT-over-DS is enabled') disabled RRB l2_packet socket
if ft_over_ds is disabled, but this socket is required for FT
over-the-air, too (FT key distribution). Enable the socket regardless of
ft_over_ds setting if FT is enabled.
