meson: Don't unnecessarily fallback to libyuv wrap

Before commit eeaa7de21b8c ("libcamera: pipeline: Add test pattern for
VirtualPipelineHandler") the libyuv dependency was only needed for the
Android adaptation layer. As libyuv isn't packaged by most distribution,
meson fell back to using a meson wrap if the Android adaptation layer
was enabled and the library wasn't found.

With commit eeaa7de21b8c, libyuv is also used by the virtual pipeline
handler, and the meson wrap fallback handling got centralized and became
unconditional, so the wrap is downloaded even if the components
depending on libyuv are all disabled. This causes unnecessary downloads
at setup time, which can be problematic on build systems without an
internet connection.

Fix this by making the wrap fallback conditional on the components that
use libyuv.
