Add initial tests for the ext4l filesystem driver: - fs_test_ext4l_probe_norun: verifies the driver can probe and mount an ext4 filesystem - fs_test_ext4l_msgs_norun: verifies the ext4l_msgs env var causes mount messages to be printed The C tests use UTF_MANUAL flag and accept fs_image argument, following the pattern established by fs_basic.c. The Python wrapper creates an ext4 image and calls the C tests. Co-developed-by: Claude <noreply@anthropic.com> Signed-off-by: Simon Glass <simon.glass@canonical.com>
