We started having issues with `pkgs.dockerTools.pullImage`, were it
would fail with:
```
FATA[0000] Error loading trust policy: open /etc/containers/policy.json: no such file or directory
```
It turns out that since `skopeo` was bumped to `0.1.40`, it was
accidentally no longer being built with a default policy.
This may happen again, see https://github.com/containers/skopeo/issues/787
This makes the command ‘nix-env -qa -f. --arg config '{skipAliases =
true;}'’ work in Nixpkgs.
Misc...
- qtikz: use libsForQt5.callPackage
This ensures we get the right poppler.
- rewrites:
docbook5_xsl -> docbook_xsl_ns
docbook_xml_xslt -> docbook_xsl
diffpdf: fixup
Skopeo used by our docker tools was patched to work in the build
sandbox (it used /var/tmp which is not available in the sandbox).
Since this temporary directory can now be set at build time, we remove
the patch from our docker tools.
