[PATCH 2/3] pwclient: use print_function for better py3 compatibility

[Mike Frysinger]

From: Mike Frysinger <vapier at chromium.org>

The script already tries to use print like a function in many places but
is really passing a parenthesized string.  Import the print_function from
the future module so that it actually works as intended.

We also need to fix up a few latent print statements to make it work.
