tests/lcitool: Do not use a hard-coded /usr/bin/python3 as python interpreter

When running "make lcitool-refresh", this currently uses the hard-coded
/usr/bin/python3 from the script's shebang line for running Python.
That's bad, since neither /usr/bin/python3 is guaranteed to exist, nor
does it honor the python interpreter that the user might have chosen
while running the "configure" script. Thus let's rather use $(PYTHON)
in the Makefile, and improve the shebang line in the script in case
someone runs this directly.
