set up python in PATH, ensuring that it is python3 

we already check the python version, and set a variable
for it, so that we can reliably use python3, even if
python in PATH doesn't correspond to python3. for
example if a system has python as python2 and python3
as python3

well, we use that when running deguard for example, but
various upstream projects that we use may need python,
and all of them use python3, not 2

so, re-use the python variable set up by lbmk, and
set it up in PATH accordingly. this now makes the note
about python3 obsolete, on docs/build.md in lbwww.git
