Subject: [PATCH] CI: show the version of the tools we use

We have failures on Flex output, which are probably related to an old
release.  Let's check.

    In file included from src/scan-code-c.c:3:
    src/scan-code.c:2198:21: error: empty paragraph passed to '@param' command
          [-Werror,-Wdocumentation]
     * @param line_number
       ~~~~~~~~~~~~~~~~~^

* .travis.yml: here.
