Add an option to propagate `--always-copy` to `virtualenv`

See original GitHub issue

Some packages (sip from PyQt in my case), are installing some header files in the virtualenv, currently the include/ folder is symlinked to the system non-nt one, and so non writable.

The virtualenv script offers the --always-copy option (active by default on nt systems) to copy all the files.

The pew script by default forwards all the unknown arguments to virtualenv.

I have the local patch working because I’d like to use pipenv in my project.

NOTE: venv has a different argument, --symlinks / --copies, with the same use, but pew currently uses virtualenv.

add --always-copy option to pipenv install
add PIPENV_ALWAYS_COPY env var
add tests

Just to avoid some more search:

env VIRTUALENV_ALWAYS_COPY=1 pipenv install

now does the trick.

If someone struggling with this nowadays, I found the bug in newer version of virtualenv. You should use alias instead of VIRTUALENV_ALWAYS_COPY:

env VIRTUALENV_COPIES=1 pipenv install
