Add a config option to build the python bindings for i2c-tools -
py-smbus. The steps for building the python bindings is the same as
the distutil steps that are a part of the python infrastructure.

Changes v2 -> v3:
- Removed Config.in entry (suggested by Baruch)
- Moved install and build defines with the CMD block (suggested
by Yann)
Changes v1 -> v2:
- Fixed spelling in config entry
- Utilize the python infrastructure variables for environment and
build/install opts (suggested by Thomas P)
- Only support python2.7 since this is not compatabile with python3
(suggested by Baruch)
