build: prefer python3.4 even if newer versions are present on the system

Browse source 
Python 3.4 is the mimimum supported version according to doc/dependencies.md

Systems with PyEnv ensure (via .python-version) that Python 3.4 is used
for the functional tests. However make check calls bitcoin-util-test.py
using the Python command found by configure.ac, which looks system wide.

On systems with multiple versions of Python this would cause make check
to fail, as it tries to call a version of Python that PyEnv blocks.

This is solved by preferring python3.4 in configure.ac
