The `ExposureTimeMode` is currently set up incorrectly in a UVC
camera's `ControlInfo`, setting it also does not work correctly.

Changes in v3:
  * fix default value: set it based on the v4l2 default
  * store current value of `ExposureTimeMode`
  * fix https://bugs.libcamera.org/show_bug.cgi?id=242 as well

Changes in v2:
  * split into two patches
  * make it compile with old libstdc++ when _GLIBCXX_DEBUG is set

v2: https://patchwork.libcamera.org/project/libcamera/list/?series=5006
v1: https://patchwork.libcamera.org/project/libcamera/list/?series=4974
