David Edmondson b6489ac066 test-coroutine: Add rwlock downgrade test 
Test that downgrading an rwlock does not result in a failure to
schedule coroutines queued on the rwlock.

The diagram associated with test_co_rwlock_downgrade() describes the
intended behaviour, but what was observed previously corresponds to:

| c1     | c2         | c3         | c4       |
|--------+------------+------------+----------|
| rdlock |            |            |          |
| yield  |            |            |          |
|        | wrlock     |            |          |
|        | <queued>   |            |          |
|        |            | rdlock     |          |
|        |            | <queued>   |          |
|        |            |            | wrlock   |
|        |            |            | <queued> |
| unlock |            |            |          |
| yield  |            |            |          |
|        | <dequeued> |            |          |
|        | downgrade  |            |          |
|        | ...        |            |          |
|        | unlock     |            |          |
|        |            | <dequeued> |          |
|        |            | <queued>   |          |

This results in a failure...

ERROR:../tests/test-coroutine.c:369:test_co_rwlock_downgrade: assertion failed: (c3_done)
Bail out! ERROR:../tests/test-coroutine.c:369:test_co_rwlock_downgrade: assertion failed: (c3_done)

...as a result of the c3 coroutine failing to run to completion.
