nat/vty: Fix construct not working with python 2.6

Use the simpler approach and just call encode('hex') on the str and
then convert it to lower case to keep the tests working.

reproduce:

Python 2.6.6 (r266:84292, Dec 27 2010, 00:02:40)
[GCC 4.4.5] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> d = '\0\0'
>>> d
'\x00\x00'
>>> "".join("{:02x}".format(ord(c)) for c in d)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 1, in <genexpr>
ValueError: zero length field name in format

fixes:
