Exclude Acala tests from CI runs

The chopsticks-side patch in this PR raised `rpcTimeout` to 90s, but
Subway hardcodes its own per-upstream `request_timeout` to 30s (with
no field exposed in `ClientConfig` to override it). Heavy Acala
storage queries take longer than 30s, so Subway cycles through the 3
Liebi endpoints (~30s each) without serving a response, and chopsticks
times out before the cycle completes.

Excluding Acala suites until Subway exposes `request_timeout` as a
config field.
