Option 2 it is then.

It turns out that libxl causes abi-dumper to churn for ~4s or so, which
isn't ideal.  All the other libraries are in the noise.

If we are going for a check-by-default policy, then we obviously need to
exclude the non-stable libraries by default.

However, to fix problems pertaining to the unstable libraries,
downstreams do need to be able to invoke checking on the other libraries
as well.

I'll have a think as to how best to make that happen.
