Add Travis CI support for arm64 architectures (hardbyte#705)

karlding · web-flow · commit 01bb3e974cce · 2020-11-26T08:51:04.000+13:00
Add support for the arm64 architecture from Travis CI's alpha offering.
This enables the test suite to run within an arm64 LXD container (minus
the tests that exercise SocketCAN, as the image is missing the required
kernel modules).
