When `libyuv` is built with `jpeg` support it does not directly link
`libjpeg` in any form. As a result dynamic loading of the library
fails as:
>>> import pillow_avif._avif
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: /usr/lib/libyuv.so: undefined symbol: jpeg_resync_to_restart
We can reproduce the same problem at build time if we build `libyuv` with
`LDFLAGS=-Wl,--no-undefined`:
[ 99%] Linking CXX executable yuvconstants
ld: CMakeFiles/yuv_shared.dir/source/mjpeg_decoder.cc.o: in function `libyuv::MJpegDecoder::MJpegDecoder()':
mjpeg_decoder.cc:(.text+0xfc): undefined reference to `jpeg_resync_to_restart'
ld: mjpeg_decoder.cc:(.text+0x136): undefined reference to `jpeg_std_error'
ld: mjpeg_decoder.cc:(.text+0x194): undefined reference to `jpeg_CreateDecompress'
The change links `libgpeg` against `libyuv` itself to make it a
self-contained library. This fixes both loading if the library
itself and fixes linking of the library against other binaries
without explicit need for passing `-ljpeg`.

libyuv is an open source project that includes YUV scaling and conversion functionality.
- Scale YUV to prepare content for compression, with point, bilinear or box filter.
- Convert to YUV from webcam formats for compression.
- Convert to RGB formats for rendering/effects.
- Rotate by 90/180/270 degrees to adjust for mobile devices in portrait mode.
- Optimized for SSSE3/AVX2 on x86/x64.
- Optimized for Neon on Arm.
- Optimized for MSA on Mips.
