android: camera_capabilities: Fix GCC 14 warning

GCC 14 thinks `rects` is a "possibly dangling reference to a temporary":

/libcamera/src/android/camera_capabilities.cpp: In member function ‘int CameraCapabilities::initializeStaticMetadata()’:
/libcamera/src/android/camera_capabilities.cpp:1084:46: error: possibly dangling reference to a temporary [-Werror=dangling-reference]

      |                                              ^~~~~
/libcamera/src/android/camera_capabilities.cpp:1085:83: note: the temporary was destroyed at the end of the full expression ‘(& properties)->libcamera::ControlList::get<libcamera::Span<const libcamera::Rectangle> >(libcamera::properties::PixelArrayActiveAreas).std::optional<libcamera::Span<const libcamera::Rectangle> >::value_or<libcamera::Span<const libcamera::Rectangle> >(libcamera::Span<const libcamera::Rectangle>())’

The return value of `value_or()` is indeed a temporary, but binding it
to a reference extends its lifetime. Avoid the warning by not using a
reference; this does not make much difference since `value_or()` does
not return a reference.
