dpdk: fix compile

Type: fix

Since DPDK is now compiled by meson but some compiles in VPP is
missing. This patch fixes that.

- Fixes QAT PMD not compiled. QAT meson compile, even for sym
crypto PMD, is happened in drive/compress/qat. Originally all
PMDs in compressdev is disabled by default. This patch fixes
that.

- Fixes DPDK plugin version detection. DPDK meson build
generates rte_build_config.h, which containing all version
information in build-dpdk instead of rte_config.h in make.
This patch uses the file to detect version data.

- Removed SW crypto PMD auto-creation in cryptodev engine. In
case the AESNI-MB PMD required shared library is missing.
