Adding support for power(ppc64le) for travis builds

[ghatwala]

Hi All,

I have added support for power ( ppc64le ) arch on travis-ci builds via my forked repository - https://github.com/ghatwala/fluentd-docker-image

The travis-ci job url - https://travis-ci.org/ghatwala/fluentd-docker-image/builds/389559309 . As can be seen in this job, the versions which failed on power are failing on Intel as well.

For example gpg keys errors seen.
For v1.1/debian -
Intel - https://travis-ci.org/ghatwala/fluentd-docker-image/jobs/389559316#L975
Power - https://travis-ci.org/ghatwala/fluentd-docker-image/jobs/389559330#L1001

To add support for power for travis build, had to make the following changes.

1. travis.yml - Ensuring that builds are routed to travis-power along with travis-intel

os:
  - linux
  - linux-ppc64le

And to make the dockerfile build for power ....

1. Dockerfile ( for debian based only ) - Dumb-Init version has been updated from 1.2.0 --> 1.2.1 as power binaries are now available for this release - https://github.com/Yelp/dumb-init/releases/tag/v1.2.1.

ENV DUMB_INIT_VERSION=1.2.1

let me know if your views/suggestions/comments if any , so that i can raise a PR to get this going ?

Regards,
Amit

@repeatedly - any comments on the above ?

gpg error is key server side issue so it seems no problem for me.

[ghatwala]
