test: run instantiateStreaming-bad-imports WPT

This test was skipped after hangs with V8 11.2. The associated compiler
shutdown deadlock involved NodePlatform::DrainTasks waiting for worker
tasks that needed garbage collection on the blocked main thread.

Since 5fb879c, DrainTasks only waits for user-blocking tasks, which
excludes ordinary background compilation. Remove the obsolete skip.
