pgAdmin 4 commit: Resolved an issue finding the python interpreter on *

Resolved an issue finding the python interpreter on *nix systems, and
Windows 2008 R2 (32 bit), while running the pgAdmin 4 as runtime for
the PostgreSQL one click installers.

- Found a typo in runtime code, we were appending the path using ';' on
*nix systems too. We should have used ':', and that did not allow the
os.environ['PATH'] to identify the correct path of the python
interpreter under the 'venv' directory.

- On Windows 2008, it was not honouring the environment variables, set
under the Qt application (e.g. pgAdmin4.exe runtime), in the python
application. (e.g. pgAdmin4.py). We will need to assume that - the
python interpreter resides under the 'venv' directory outside the
'bin' directory.

- Also, on windows 2008, it was setting PYTHONHOME environment variable
to the full path of the pgAdmin4.exe, we need to reset it to 'venv'
directory, if we find the python interpreter under it.

Thanks Murtuza Zabuawala for tips, and help.
