wally: Specify that we use python3 so we don't depend on python2

Browse source 
We specify `PYTHON_VERSION=3` to prevent libwally's ./configure from searchin
for python2, which some distros have started removing, and we were requiring
it only for the configuration step anyway.

Changelog-Changed: dependencies: We no longer depend on python2 which has reached end-of-life
