[Distutils] why do we still put version numbers into dist-info folders

[Daniel Holth]

A long time ago pkg_resources was able to sometimes get the version number
only from the .egg-info folder name, and skip opening the metadata at all
when that data was not needed. We might always do listdir() for path in
sys.path and parse every METADATA on the first pkg_resources import.
