Add getsitepackages() to site module (Issue #355)

[tomshen]

This is part of a fix for issue #355. Since virtualenv has its own implementation of the site module, and since it lacks all the functions added past Python 2.6, I thought it might be useful to start adding those functions in. This one in particular has been specifically requested (#228).

I am struggling with the same issue that this PR is trying to solve. Any chance this will be merged at some point?

Hello!

As part of an effort to ease the contribution process and adopt a more standard workflow virtualenv has switched to doing development on the master branch. However, this Pull Request was made against the develop branch so it will need to be resubmitted against master.

If you do nothing, this Pull Request will be automatically migrated by @BrownTruck for you.

If you would like to retain control over this pull request then you should resubmit it against the master branch, closing and referencing the original Pull Request.

If you choose to migrate this Pull Request yourself, here is an example message that you can copy and paste:

*This was migrated from pypa/virtualenv#508 to reparent it to the ``master`` branch. Please see original pull request for any previous discussion.*

If this pull request is no longer needed, please feel free to close it.

Anybody know what the workaround for this is ?

[gaborbernat]

Newer virtualenv no longer patches site.py so this issue should no longer be relevant.

Cheers, I was on travis and managed to miss this.
