feat(LSP): Refactor alternative executables for linters 

Test for new executables, for different checkers, for Python LSP only if
the virtual environment directory has been found.

The previous behavior could have found executables for such linters on
different places, as they could have been appearing outside a virtual
environment directory (if the `venv_dir` variable tested as an empty
string).  Such behavior could lead to undefined behaviors.
