Vadim Zeitlin 2782377d4f Switch Ubuntu 18.04 CI builds to newer Ubuntu versions ...

Don't use the old Ubuntu version, Ubuntu PPAs are simply too flaky to be
used.

Use the latest available Ubuntu image (26.04) for all builds except
wxDFB as libdirectfb-dev package is not available in this Ubuntu version
any longer, so use 24.04 for this job.

Remove special handling of Ubuntu 18.04 which is not needed any more.
