Packages not installed on virtual env if existant on local env

[Skiktlle]

Issue description

Tried to run some code to get me a list of github repos. For that I need all packages that PyGithub downloads.
If, for example, I have certifi package already on my original python site-packages directory and I run pipenv install for PyGithub, the certifi package won't be installed on the newly created virtual env.

Expected result

I expected that the packages already installed in original env would also be installed on virtual environments if they don't have it.

Actual result

The packages already existing in the original env, will not be installed on the virtual env.

Steps to replicate

1. pip install pipenv

2. pip install certifi

3. pipenv install

4. Check that inside site-packages on virtual env there is no certifi package.
5. Try to run main.py inside virtual env => Should result in ModuleNotFoundError.

Pipfile

[[source]]
url = "https://pypi.org/simple"
verify_ssl = true
name = "pypi"

[packages]
PyGithub = "==1.55"`

main.py

from github import Github

g = Github("your account token")

for repo in g.get_user().get_repos():
print(repo.name)

@Skiktlle I believe this is essentially the same issue as #5254
but you have generalized it nicely.

Can you check my branch that tries to fix this issue, if it resolves the issue for you? This is the branch: #5255
