[dpdk-dev] [PATCH v4 2/4] build: use Python pmdinfogen

[Dmitry Kozlyuk <dmitry.kozliuk@gmail.com>]

Like for other build scripts, use Python interpreter to run pmdinfogen.
Adjust wrapper script accordingly and also don't suppress stderr from ar
and pmdinfogen.

Add python3-pyelftools to CI configuration.
