consistent functionality test failures on `ubuntu-latest`

[andrurogerz]

Since nightly build/test run #161 , the Test Linux x86_64 functionalities and Test Android x86_64 functionalities jobs have been failing. The timing of the failures coincides exactly with the move of ubuntu-latest to run on Ubuntu 24.04.1 LTS when they were previously running on Ubuntu 22.04.5 LTS.

There are two new test cases that fail consistently in both of these jobs: TestDataFormatterSynthVal.DataFormatterSynthValueTestCase.test_with_run_command_dwarf and TestDataFormatterSynthVal.DataFormatterSynthValueTestCase.test_with_run_command_dwo. These are two variants of the same test case.

Example failure log:
