fixes uri construction so path is preserved

If the repository content is anywhere other than "/" in the server root, pkg
doesn't work properly.

As an example, take repository: 
http://pkg.opensolaris.org/webstack/

After creating an image using it,
# pkg image-create -F -a webstack=http://pkg.opensolaris.org/webstack/ /
if one attempts to 'pkg install' something, pkg drops the "/webstack" part
when issuing requests to the server, so nothing matches.

I found that the info is being lost in modules/misc.py while constructing the
uri.

The attached patch constructs the uri preserving the full path.

Note: I don't really speak python so this may or may not be the right way. I
just copied style seen elsewhere in the file. 

With this patch, pkg can now install packages off
http://pkg.opensolaris.org/webstack/
