PTXdist (or rather kconfig) does not have a notion of "provides" or
metapackages. I think is currently no way other than making a choice
option that selects the one or the other, or letting your config option
deoend on BUSYBOX_OPENVT || KBD_OPENVT. In the latter case it is
probably good to add a comment above it that depends on the opposite
value notifying the user that neither one of them is selected (see the
comment above IPTABLES_INSTALL_IPTABLES_APPLY in iptables.in for
example).
