Don't fail when rpm is not installed

In environments where rpm is not available, the
TestRunner.LogEnvironment method throws an exception:

    Unhandled exception: System.ComponentModel.Win32Exception (2): An
    error occurred trying to start process 'rpm' with working directory
    'Samples'. No such file or directory

The code tries to handle these environments (like alpine), but doesn't
catch the actual Win32Exception thrown when the rpm command is not
found. It only catches InvalidOperationException (which happens when rpm
command exits with an error).

Also update CI to catch issues like this by adding an alpine leg.
