Create omniorb-libs subpackage to allow installing the libs without any Python dependency.

This should be OK now. My first try didn't work because globs aren't supported for directories in the files output. I had to change lib/python*/site-packages/omniidl to lib/python{{ PY_VER }}/site-packages/omniidl + add explicitly some directories under include. I checked the Linux packages. The total number of files is 30 in omniorb-libs + 398 in omniorb. This matches the number of files in the current package (428).

I added omniorb-libs as run_exports. When compiling a package with omniorb as host dependency, only omniorb-libs is required at runtime.

This should fix #15

I also added myself as maintainer as you proposed.

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) and found it was in an excellent condition.
