Missing dependencies in recent master containers

[patrick-stephens]

Bug Report

Describe the bug

Recent container images are showing failures with dependencies when running schema or help output:

docker run --rm -it ghcr.io/fluent/fluent-bit/unstable:master --help
...
/fluent-bit/bin/fluent-bit: error while loading shared libraries: libldap_r-2.4.so.2: cannot open shared object file: No such file or directory

The following versions are fine:

• fluent/fluent-bit:2.1.2
• fluent/fluent-bit:2.0.11
• ghcr.io/fluent/fluent-bit/unstable:2.0

It therefore seems to be an issue with a recent merge to master as the 2.0 branch is ok.

To Reproduce

Run a container built from master, e.g.

$ docker run --pull=always --rm -t ghcr.io/fluent/fluent-bit/master:x86_64 --help
Unable to find image 'ghcr.io/fluent/fluent-bit/master:x86_64' locally
x86_64: Pulling from fluent/fluent-bit/master
...
Digest: sha256:fe576aa51c55acc70b3cd2b4de5ad2f202ff6e8e3ecab2a475da6ca470e42275
Status: Downloaded newer image for ghcr.io/fluent/fluent-bit/master:x86_64
/fluent-bit/bin/fluent-bit: error while loading shared libraries: libldap_r-2.4.so.2: cannot open shared object file: No such file or directory

Expected behavior

Additional context

I think this is triggered by #7309 - we updated the production container to use the latest LDAP (2.5.0) but not the builder container so it is depending on the old version of 2.4.
