* libvips: add pdfium to build
Many Rails users will shortly be switching to libvips pdfium load for
PDF rendering. pdfium is well tested and doesn't need fuzzing itself,
but we do need to fuzz the code that links libvips to pdfium.
This PR adds pdfium nightly builds to the libvips fuzzer.
* fix pdfium download
* ooop missing RUN
* fix pdfium install
* Fix PDFium link
* layout

- Re-order linker flags.
- Use libbrotli from system.

* libvips: add lcms and libspng as dependencies
* libvips: fix AVIF fuzzer
- Ensure libheif is able to detect the headers provided by libaom.
- Disable the build of dynamic modules.
* libvips: fix JXL fuzzer
* fix link failure with libtiff
The fuzz targets were failing to link with:
```
Step #4: /work/lib/libtiff.a(tif_lzma.o): In function `TIFFInitLZMA':
Step #4: /src/libtiff/libtiff/tif_lzma.c:465: undefined reference to
`lzma_lzma_preset'
```
It looks like it's become necessary to explicitly link -llzma, see:

Thanks to @lovell.
* pin libtiff to 4.1.0
It seems there's an issue with git master libtiff -- it fails to link on
systems without lzma installed.
For now, pin to 4.1.0, the current stable version.
* explicitly disable lzma
lzma detection in libtiff seems to be broken as of 20 nov. Disable
explicitly.
