cam: file_sink: Workaround gcc-13 dangling-reference false positive
A new warning has been introduced to gcc-13 that produces a false
positive on the cam file sink object:
src/cam/file_sink.cpp:92:45: error: possibly dangling reference to a temporary [-Werror=dangling-reference]
92 | const FrameMetadata::Plane &meta = buffer->metadata().planes()[i];
| ^~~~
src/cam/file_sink.cpp:92:81: note: the temporary was destroyed at the end of the full expression '(& buffer->libcamera::FrameBuffer::metadata())->libcamera::FrameMetadata::planes().libcamera::Span<const libcamera::FrameMetadata::Plane>::operator[](i)'
92 | const FrameMetadata::Plane &meta = buffer->metadata().planes()[i];
| ^
cc1plus: all warnings being treated as errors
Workaround this issue by refactoring the code to take a local const
copy of the bytesused value, rather than a local const reference to the
plane.
