Auto-detect python binary

We now try whether there is an executable called python2, and if so,
use that in preference to python when executing the metric computation.
Furthermore, we allow the user to specify the path of the python binary
using the PYTHON variable of make, i.e. “make PYTHON=/foo/python2 metrics”.
