tcpreplay: fix CI tests for the QEMU runtime

The generic per-executable version probe and the old test.sh both invoke
tcpreplay --version. Under the QEMU test runtime tcpreplay and
tcpreplay-edit abort at startup on the interface link probe
("eth0: SIOCETHTOOL(ETHTOOL_GLINK) ioctl failed: Not a tty") before
autoopts can print the version, which fails the tcpreplay-all test and
warns on the standalone tcpreplay/tcpreplay-edit packages.

Add a test-version.sh that disables the flaky generic probe and asserts
each tool's version without needing an interface, and rewrite test.sh to
exercise the file-processing core (tcpcapinfo dissect, tcprewrite edit,
tcpprep cache) on a small synthesized capture instead of shelling out to
--version, which the CI infrastructure already covers.
