Collection: Include <cstdint>.

[Gacko]

This fixes builds on Alpine v3.23.0 (GCC v15.2.0, musl v1.2.5).

headers/modsecurity/collection/collection.h:x:x: error: 'int32_t' has not been declared
headers/modsecurity/collection/collection.h:x:x: note: 'int32_t' is defined in header '<cstdint>'; this is probably fixable by adding '#include <cstdint>'

Just a side note: the referenced type (int32_t) is used here.

And one question: is there no other file where it is missing?

I haven't checked, but we're relying on it in Ingress NGINX and this change made the build of our NGINX base image work: https://github.com/kubernetes/ingress-nginx/blob/main/images/nginx/rootfs/build.sh#L337-L367.
