[fix] Add each .egg and .dist-info to environment

Since zc.buildout uses `pip` to install dists, most .egg in ./eggs and
./develop-eggs (in case of dists installed with zc.recipe.egg:custom)
are not actually eggs, but installed wheels with .dist-info format
which have been bundled into a .egg containing .dist-info metadata
folder as well as the actual package folder directly alongside.

Unlike actual eggs, such */*.dist-info bundles are not stepped into
by package_resources when the containing directory is add to the
environment, so each .egg bundle needs to be added individually.

Buildout already does this for bundles in the target directory of
egg installation, usually ./eggs, but e.g. in offline mode there
is no target directory and then already installed .egg bundles
are not detected.

So now every dist path is added to the environment individual,
including for paths where buildout looks for already installed
eggs but will not install eggs to, such as ./develop-eggs, and
also ./eggs in offline mode or when using zc.recipe.egg:custom
and the target is ./develop-eggs and ./eggs is such a scan-from
but don't-install-to path.
