ci: run aarch64 compile tests on Drone

Besides Travis CI Drone CI seems to be only service providing ARM based
builds. This switches the aarch64 and arm32 builds to drone.io.

Because Drone CI is running in a Docker container we cannot use 'setarch
linux32' as it requires the blocked syscall 'personality(2)'.

But Drone CI provides an 'arch: arm' which gives the same architecture
as 'setarch linux32' on Travis aarch64: armv8l
