cmd/cue: skip the mod_registry testscript as it's flakey
Until I've finished a change to testscript to add a `waitmatch` command.
Otherwise the CI runs fail about 2-5% of the time with:
> exec cue mod registry ${CUE_REGISTRY} &
> exec cue mod publish v0.0.1
[stderr]
cannot put module: [...]: dial tcp [::1]:41331: connect: connection refused
[exit status 1]
