[PATCH] libcamera: meson: Fix libyuv detection

[Kieran Bingham]

From: Dylan Aïssi <daissi at debian.org>

We already fall back to a subproject to support the libyuv package when
it can not be discovered through the usual dependency() mechanism.

Unfortunately libyuv may be packaged without any corresponding
pkg-config support as can be seen at [0], so further extend the
dependency search by using an explicit cc.find_library() call.
