lang/python{27,33,34,35,36}: Make Python curses module work with Unicode

Use readline from ports (USES= readline:port) and patch
setup.py to ignore readline from base. The patch is necessary for
FreeBSD < 1100000, as after this the readline library became an
INTERNALLIB, see base r268461 [1]

Link devel/readline against termcapw instead of termcap is part of
this change, see ports r444463 [2]

Note that this is the **ports** approach for getting Python curses
module working with Unicode. The other way is splitting libncurses
into separate libncurses and libtinfo in base, for which an open
issue exists [3].

Apart from Python language ports, at least www/rtv and
sysutils/py-ranger ports have been tested to work correctly
(display Unicode) after this change.
