refactored compose run linux tests to nerdtest.Setup

Migrated 9 out of 10 tests in compose_run_linux_test.go from legacy
testutil.NewBase to the nerdtest/tigron framework. Replaced unbuffer
wrapper with WithPseudoTTY, goroutine polling with cmd.Background
and EnsureContainerStarted, and hardcoded ports with portlock.Acquire.
