This prevents --pause-isolates-on-start and --pause-isolates-on-exit
from impacting isolates spawned from system isolates. This should be
revisited to determine if:
- Inheriting the system isolate property is actually what we want to do
in general
- Isolate.spawn* APIs should instead include a parameter to specify an
isolate as a system isolate
