[PATCH] oeqa/runtime: fix race-condition in minidebuginfo test

[ecordonnier@snap.com]

From: Etienne Cordonnier <ecordonnier@snap.com>

Fix this error where 'coredumpctl info' warns that the coredump is still being
processed:

```
AssertionError: 1 != 0 : MiniDebugInfo Test failed: No match found.
-- Notice: 1 systemd-coredump@.service unit is running, output may be incomplete.
```
