[PATCH 1/1] autogen.sh: detect python3

[Heinrich Schuchardt]

On some current distributions there is no /usr/bin/python. The Python
binary is /usr/bin/python3. If a command python3 is available, use it
instead.

I prefer solution proposed here [1]. Of course with some changes
discussed in the thread.
