This greatly improves the performance of `pyenv virtualenvwrapper_lazy`,
which happens to call pyenv-which a lot.
For profiling I've initially used:
% zmodload zsh/zprof
% eval "$(pyenv init -)"
% pyenv virtualenvwrapper_lazy
Before:
% zprof|grep -E '(pyenv|virtualenv)'
1) 1 754,07 754,07 58,95% 751,50 751,50 58,75% pyenv
21) 1 2,57 2,57 0,20% 2,57 2,57 0,20% virtualenvwrapper_setup_lazy_loader
1) 1 754,07 754,07 58,95% 751,50 751,50 58,75% pyenv

21) 1 2,57 2,57 0,20% 2,57 2,57 0,20% virtualenvwrapper_setup_lazy_loader
After:
% zprof|grep -E '(pyenv|virtualenv)'
1) 1 383,30 383,30 27,97% 380,88 380,88 27,79% pyenv
