PSA: it is getting increasingly easy for functional tests to be silently (technically not silently, but who notices the stray line in the cmake barf) skipped. Originally, it was just requiring python requests, which is hard needed for RPC comms, but now some random modules will also kick functional tests from being run even though they're neeed for a single test: zmq, deepdiff, or even not a single

test: psutil, monotonic.

TF may be more dependent than monero on functional tests, but this is a bad way to be going. Skip just the bits that need to be, not the whole tests.
