libpq: Remove server-based files from client library package

- Remove postgres.bki and system_constraints.sql files from package
- These files are server-specific and should not be included in the client library
- Fixes issue introduced by previous rebase to PostgreSQL 18.0

Resolves packaging inconsistency where server files were incorrectly
included in the client library package.
