build: Temporarily drop the MSHV CI jobs

These fail more than they pass due to infrastructure reasons (rather
than tests failing) and so because they are constantly seen as failing
they are ignored (i.e. alarm fatigue).

It is better not to run them until the infrastructure issues have been
fixed.
