No module named `pkg_resources`

Looks like the deprecation finally turned into removal of `pkg_resources` from setuptools. `bioconda-utils` needs to be patched to resolve this. To-do's: - [x] https://github.com/bioconda/bioconda-common/pull/80. - [x] https://github.com/bioconda/bioconda-utils/issues/1074 - [x] Bump `bioconda-utils` in https://github.com/bioconda/bioconda-common once fixed: https://github.com/bioconda/bioconda-common/pull/81 See also: - https://github.com/bioconda/bioconda-common/pull/79
