ci: drop libsframe installation step

The intent of the step was that libsframe1 should be installed when
running the workflow on the ubuntu-24.04 runner. However, the condition
mistakenly checks for the step being run on the ubuntu-20.04 runner,
so it's currently a no-op. The workflow passed without this step being
run. Thus, we can assume libsframe1 was installed as a transitive
dependency in the previous step and the libsframe installation step can
be removed altogether.
