Drop dmlc static library

Hi! This is the friendly automated conda-forge-webservice.

I've started rerendering the recipe as instructed in #236.

If I find any needed changes to the recipe, I'll push them to this PR shortly. Thank you for waiting!

Here's a checklist to do before merging.

• Bump the build number if needed

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe/meta.yaml) and found it was in an excellent condition.

I do have some suggestions for making it better though...

For recipe/meta.yaml:

• ℹ️ py-xgboost output has some malformed specs:

• In section host: `libxgboost ==cpu_h_PKG_BUILDNUM
• In section run: `libxgboost ==cpu_h_PKG_BUILDNUM
  xgboost output has some malformed specs:
• In section host: `py-xgboost ==cpu_pyh_PKG_BUILDNUM
• In section run: `py-xgboost ==cpu_pyh_PKG_BUILDNUM
  r-xgboost output has some malformed specs:
• In section host: `libxgboost ==cpu_h_PKG_BUILDNUM
• In section run: libxgboost =*=cpu_h*_PKG_BUILDNUM Requirement spec fields should match the syntax name [version [build]]to avoid known issues in conda-build. For example, instead of name =version=build, use name version.* build. There should be no spaces between version operators and versions either: python >= 3.8should bepython >=3.8`.

Could you please provide some context about this change?

I think we need some changes in the xgboost upstream CMake files.

Was just pushing some initial thoughts up

Yeah agree a CMake change is likely needed
