[PATCH v3 05/13] .travis.yml: Update the jobs to Ubuntu 22.04

[Thomas Huth]

According to our support policy, we'll soon drop our official support
for Ubuntu 20.04 ("Focal Fossa") in QEMU. Thus we should update the
Travis jobs now to a newer release (Ubuntu 22.04 - "Jammy Jellyfish")
for future testing. Since all jobs are using this release now, we
can drop the entries from the individual jobs and use the global
setting again.
