[ci][cirrus] Replace trusty with bionic/focal in debian_default_toolchain

Ubuntu 14.04 (Trusty) is out of standard support [1].
``make check`` fails for test_capabilities, as noted in [2].
[3] indicates that the cause is glibc, but that updates are not expected
to the version in trusty.

This PR replaces trusty with Ubuntu 18.04 (Bionic) and 20.04 (Focal).
