[PATCH] ci: drop Travis configuration

[David Marchand <david.marchand@redhat.com>]

We stopped using Travis in the main branch and in the public CI in favor
of GHA more than a year ago.
The UNH community lab now covers testing native compilation and unit
tests for ARM platforms.

We decided to stop maintaining the configuration in our repository with
the argument that "if it is not tested, it is broken".

 If you are using the GitHub service, pushing to a branch will trigger GitHub
 Actions to automatically build your changes and run unit tests and ABI checks.
 
-Additionally, a Travis configuration is available in DPDK but Travis free usage
-is limited to a few builds.
-You can link your repository to the ``travis-ci.com`` build service.

 The development process requires some familiarity with the ``git`` version control system.
