Drop "unstable" Debian "bullseye" unit and system jobs

"Unstable" Debian "bullseye" unit and system jobs differ from unit and
system jobs on the Debian "bullseye" image by running a few more tests
enabled by the CI_ENABLE_ALL_TESTS environmental variable.  These tests
are no less stable than the rest, and thus to have distinct jobs for
them wastes resources.

Run "unstable" unit and system tests as part of stock Debian "bullseye"
jobs.
