Laurent Pinchart e4d2dcc549 libcamera: media_device: Fallback to legacy ioctls on older kernels

Prior to kernel v4.19, the MEDIA_IOC_G_TOPOLOGY ioctl didn't expose
entity flags. Fallback to calling MEDIA_IOC_ENUM_ENTITIES for each
entity to retrieve the flags in that case.

Fixes: 67d313240c ("libcamera: pipeline: uvcvideo: create a V4L2Device for the default video entity")
