[dpdk-dev] [PATCH 1/2] test: use env variable to run tests

[Harry van Haaren]

With this patch the test binary checks the DPDK_TEST
environment variable and if set, the contents of the var
are inserted on the test app command line, and run.

Note that this patch is the combination of multiple patches
that were developed on the dpdk-next-build tree, however the
changes target code for mainline DPDK.

As such, the relevant parts of the following commits were
merged into this single patch that targets mainline:
- 32529 test: use env variable to run test if set
- 32555 test/test: fix missed failures when running meson test
- 32556 test/test: add return value to mark unit tests as skipped
