The biggest user of coroutines is the block layer. So we probably
ought to have coroutines aligned with a job that triggers the
'make check-block' for iotests.  IIUC,  the without-defaults
job won't do that. How about, arbitrarily, using either the
'check-system-debian' or 'check-system-ubuntu' job. Those distros
are closely related, so getting sigaltstack vs ucontext coverage
between them is a good win, and they both trigger the block jobs
IIUC.

Incidentally sigaltstack is also covered by our Cirrus CI job
for macOS.
