community/cloudi: Disable tests

I noticed the build failure at https://build.alpinelinux.org/buildlogs/build-edge-x86_64/community/cloudi/cloudi-2.0.0-r0.log and that is a previously reported problem at #11474 (closed)

With Erlang/OTP 23.0, it should have less problems with LXC container use if the container is setup with limits.cpu config. I set the test timeout to 10 minutes but that didn't avoid the build bot error (bare-metal use uses 10 seconds).

@Leo Please tell me what you think. Thanks and sorry for the update/merge problems.
