Update .travis.yml

[nageshlop]

This PR adds CI support for the IBM Power Little Endian (ppc64le) architecture. The idea is to ensure that the builds on this architecture are continuously tested along with the Intel builds (amd64) as this is part of the ubuntu distro on that architecture as well and detecting (and fixing) any issues or failures early would help to ensure that we are always up to date.
The build and test results are available at the below location.

Any idea why this is failing in master for Ruby 2.4.x?
https://travis-ci.com/github/K-and-R/email_validator

I am seeing that the activerecord is pulled in at version 5 for amd64 but pulled it at version 6 for ppc64le. For Ruby versions > 2.4, the version 6 is fine, as is expected. This was not occurring in the PR branch, nor in develop when the PR was merged into the develop branch. This is only now happening in master after this commit was merged into master.

In the non-master builds, Bundler was pulling in version 5 of ActiveRecord for the Ruby version 2.4.x.

I suspect that I may be able to just rebuild this failed build and possibly have it work, however TravisCI is apparently broken at the moment: https://travis-ci.community/t/oh-no-an-error-occurred-the-job-could-not-be-restarted/11193

Hi @karlwilbur
I verified the test by executing travis build on master branch. I was also observing timeout issue, after retrying the build it is successful. Looks intermittent issue in connecting host. Could you rerun the build and check. The build logs are as mentioned below.
Successful build log:
https://travis-ci.com/github/nageshlop/email_validator/builds/222362933
Error:

I am going to create an issue for tracking this.
