package/v4l2loopback: enable CONFIG_MEDIA_CAMERA_SUPPORT kernel option

Browse Source 
Setting CONFIG_VIDEO_DEV is no sufficient as drivers/media/Kconfig has
some very convoluted logic to hide some options behind a
CONFIG_MEDIA_SUPPORT_FILTER option, unless CONFIG_EXPERT is
enabled. Due to this, several arch defconfigs don't have
CONFIG_VIDEO_DEV enabled when doing $(call
KCONFIG_ENABLE_OPT,CONFIG_VIDEO_DEV).

To fix this, we enable one of the possible options that ensures
CONFIG_VIDEO_DEV is enabled, and we've more or less arbitrarily chosen
CONFIG_MEDIA_CAMERA_SUPPORT.

We've tried to track down which kernel version introduced this
exactly, but it's been introduced a while ago and step by step making
it difficult to pin-point which version version exactly introduced
this. But the issue has been appearing for quite some time in the
autobuilders, so it's clearly not a recent issue.
