Subject: [PATCH 4/5] :construction_worker: Exclude zlib-ng feature on RISC-V
 due to unaligned memory access

zlib-ng has unresolved RISC-V issues (heap corruption from unaligned
fastbin chunks) even in latest version (2.3.3). Skip zlib-ng feature
in RISC-V test matrix until upstream fix is available.
