[dpdk-dev] [PATCH 2/2] crypto/aesni_mb: cleanup of version check code

[Bruce Richardson]

The version check for the IPSec_MB library present in the aesni_gcm
library's meson.build file is a little cleaner than that given here,
so update this one so that both work identically.

While one could use the checks done in the other right now, potentially in
future they may have different version dependencies, or may be compiled in
different orders, so keep the code duplicated for safety, since it's only a
few lines.
