text: Title: Regression for usage of pip options
  Body: ## Issue
  
  Since version 4.0 tox fails when encountering pip options as part of the dependencies.
  
  The following example works fine with tox <4.0, but doesn't work with tox >=4.0 anymore.
  
  ```
  $ cat requirements.txt
  --no-binary pydantic
  $ cat tox.ini 
  [tox]
  envlist = py3
  
  [testenv]
  deps = -r requirements.txt
  
  allowlist_externals = echo
  
  commands = echo "hello world"
  $ tox --version
  4.2.1 from /home/user/.local/lib/python3.10/site-packages/tox/__init__.py
  $ tox -r
  py3: remove tox env folder /dir/.tox/py3
  py3: failed with argument --no-binary: invalid choice: 'pydantic' (choose from ':all:', ':none:') for tox env py within deps
    py3: FAIL code 1 (0.22 seconds)
    evaluation failed :( (0.33 seconds)
  ```
