Fix UBSan errors (#1948)
* Ensure UBSan exits with a non-zero code on error

* Avoid misaligned member access in mosaic_fuzzer

* Add missing VIPS_CLIP in scRGB2sRGB/scRGB2BW

* Fix UBSan error in flatten

By using saturated casts for the int types (copied from vips_cast).

* CI: ensure fuzzer log is printed on error

* Avoid UB in heifload

* Revert flatten change

I could no longer reproduce this with clang 12 locally.

* Indentation fixes [skip ci]

John Cupitt cb1634dd31 block fuzz data over 100kb
Many codecs can take a huge amount of time attempting to read large
random objects. jpeg_read_header(), for example, can take ~10s on a 1mb
of random data.

Ignore fuzz objects over 100kb.
