Subject: [PATCH] os.realname variable for correct USER_SITE value (#410)

In site.py, Python uses os.name to decide where the USER_SITE (ie the
folder containing the user's locally installed packages) is located.
With cosmo we have set os.name as "posix" always, so we use a new
os.realname to decide the USER_SITE location.
