Fix tests that don't work on aarch64 (#6630)

There's an ongoing effort to create an xcp-ng port for ARM servers, to
help maintain compatibility in the toolstack, these changes make the
tests pass on aarch64 and unblock adding CI testing on xs-opam.

Before enabling the CI in xen-api, some packages need to be removed from
xs-opam: xapi-project/xs-opam#737

I will open a PR enabling aarch64 runners on xen-api once the xs-opam
tests are passing, on both repositories the new CI is set to
experimental to avoid blocking any merges
