Give credit to zrecompile doc in zshcontrib(1)

and make code closer to the one in the manual pages (unless for our code
style). Why reinvent the wheel?

This last change makes the arguments to zrecompile shorter (passing
relative paths instead of full paths to each function file).
The number of arguments can be huge. There are 1143 of them currently
for /usr/local/Cellar/zsh/5.7.1/share/zsh/functions!
