We also disable the test in hotreload mode, because threads that are
stuck in ffi calls don't participate in hot-reload requests.
This is something we may want to look into. Right now it's conservative in
the sense that if an embedder did a `Dart_LookupClass()` in such a ffi call
and then a reload happened, such a handle would possibly hold pointer to
an old class object and weird things may happen.
This fixes test failures in hot reload / rollback mode of
`vm/dart/isolates/many_isolates_blocked_at_ffi_test`
and also make it more robust.
