afb5fca25a test: fix flaky test for issue24491
runtime.GC() doesn't guarantee the finalizer has run, so use a channel
instead to make sure finalizer was run in call to "after()".

Fixes #41361

1f45216694 cmd/compile: attach OVARLIVE nodes to OCALLxxx
So we can insert theses OVARLIVE nodes right after OpStaticCall in SSA.

This helps fixing issue that unsafe-uintptr arguments are not kept alive
during return statement, or can be kept alive longer than expected.

Fixes #24491
