Checking the past 10 builds in Travis CI arm64, it looks stable. So, disable allow_failures.
Also sorted the order of the jobs for the priority. The arm64 is the first. And I would like to run arm32 using the arm64 pipeline a bit later after the arm64 using the same arm64 pipeline. So, the arm32 is the last.
.travis.yml: Run arm64 without allow_failiures.
