[PATCH 0/1] MR9707: devenum/tests: Skip test if no video capture device is present.

[Bernhard Übelacker]

This patch copies the same skip seen in [qcap/tests/videocapture.c](https://gitlab.winehq.org/wine/wine/-/blob/master/dlls/qcap/tests/videocaptu...).

This is to avoid the test crashing with wine and windows.

[Test pattern page](https://test.winehq.org/data/patterns.html#devenum:devenum)

Followup to 9f3ca141da.
