Subject: [PATCH] handle undefined LEVEL1_DCACHE_LINESIZE

Applied-Upstream: https://github.com/OISF/suricata/pull/7350
Last-Update: 2022-06-01

On some platforms (riscv64, s390x) this value is undefined as returned from getconf.
We also need to handle this to avoid using the string undefined blindly in further
#defines, which would otherwise cause compile errors.
