[PATCH 1/3] ci: Wait for bitbake worker to finish before deleting artifacts

[Jan Kiszka <jan.kiszka@siemens.com>]

From: Jan Kiszka <jan.kiszka@siemens.com>

bitbake completes asynchronously to the worker daemon. Therefore, we
must not start deleting its tmp folder before the termination because it
may contain active mounts.

Wait for the socket that links frontend and backend to go away. This is
a reliably sign that the worker finished as well.
