run-tests: cleanup windows generation of the python / python3 pointeur
They are no need to generate then in RUNTESTDIR and we don't need a python2
executable. (because not test ever use `python2` explicitly).
This is probably still not perfect, but at least it is better.

Check that config of the source repository is also loaded

$ echo "curses=true" >> ../source/.hg/hgrc
$ hg showconfig ui.curses

Test that extensions of source repository are also loaded
$ hg debugextensions
share
$ hg extdiff -p echo
hg: unknown command 'extdiff'
'extdiff' is provided by the following extension:
extdiff command to allow external programs to compare revisions
(use 'hg help extensions' for information on enabling extensions)
[10]
$ echo "[extensions]" >> ../source/.hg/hgrc
$ echo "extdiff=" >> ../source/.hg/hgrc
$ hg debugextensions -R ../source
extdiff
share
$ hg extdiff -R ../source -p echo
BROKEN: the command below will not work if config of shared source is not loaded
on dispatch but debugextensions says that extension
is loaded
$ hg debugextensions
extdiff
share
$ hg extdiff -p echo
However, local .hg/hgrc should override the config set by share source
