test-container: add exec, cwd
exec <path_to_test_binary> [optional_argv_0] copies test binary to specified location and runs it from there. If the second argument is provided, that will be used for argv[0] cwd <directory> attempts to chdir(directory) before running test Note: "cwd" not "cd" as it takes effect just before the test binary runs, not when it's encountered in the script, so it can't be used as a path shortcut like "cd" would imply. cleanup: use xstrdup() instead of strdup() Reviewed-by: Carlos O'Donell <carlos@redhat.com>
