Require at least on curve for ECP_LIGHT
ECP_LIGHT is not usable without any curve, just the same as ECP_C.
We forgot to update this check when introducing the ECP_LIGHT subset.
Note: the message doesn't mention ECP_LIGHT as that's not a public
config knob, hence the message with "ECP_C or a subset" (that's how it's
referred to in user-facing documentation such as
docs/driver-only-builds.md).
