travis.yml: Remove the aarch64 job

According to:

 https://docs.travis-ci.com/user/billing-overview/#partner-queue-solution

only s390x and ppc64le are still part of the free OSS tier in Travis.
aarch64 has been removed sometime during the last year. Thus remove
the aarch64 job from our .travis.yml file now to avoid that someone
burns non-OSS CI credits with this job by accident now.
