    test-sysroot: Use GSystem to spawn subprocess
    
    I was getting a weird hang in the installed tests with the shell as a
    zombie process, not reaped by the parent, which was just stuck in
    select() on the output pipes.  The thing is we don't actually want to
    capture stdout/stderr, we just want to inherit.
    
    GSystem.Subprocess makes that possible, so let's just use it now that
    it's a proper installed library.
