Title: roslz4: fix a python major version check in the python module

When building I get this:

```
[100%] Building C object CMakeFiles/roslz4_py.dir/src/_roslz4module.c.o
/usr/bin/cc -Droslz4_py_EXPORTS -fPIC -I/tmp/rviz_ws/indigo/deps/src/ros_comm/roslz4/include -I/usr/local/include -I/System/Library/Frameworks/Python.framework/Headers -o CMakeFiles/roslz4_py.dir/src/_roslz4module.c.o -c /tmp/rviz_ws/indigo/deps/src/ros_comm/roslz4/src/_roslz4module.c

return m;

```

This pull request fixes this for me.
