Loading QD_jll fails

[vchuravy]

The build works fine #754, but actually loading it fails JuliaRegistries/General#12197

Uhm, we had to mark one of the products as don't dlopen, that might be the reason. I'll need to check

Ok, this is weird: the error is

[ Info: Attempting to `import` package
ERROR: InitError: could not load library "/tmp/jl_103c9s/artifacts/6e37ddbeb239f39d492e1eab1ddaf7c43b39ff59/lib/libqdmod.so"

We were already seeing this back in January (see #380 (comment)) but I thought we had fixed it 😕 Building this package has been quite a pain 😣

The build works fine #754

Actually the log shows dlopen errors, but ignores them:

I think this is again JuliaPackaging/BinaryBuilder.jl#683.
