Update recipe from marmalade-upload to marmalade-client

"upload packages to marmalade and do other things with it, from inside
Emacs." - https://github.com/nicferrier/emacs-marmalade-upload

context: marmalade-upload has been renamed to marmalade-client

I am not the maintainer.

make recipes/marmalade-client ok.

M-x package-install-file ok.

Note:
I do not know if it's a good idea to remove marmalade-upload (it's what
I did in this PR) or to have both marmalade-upload (old one) and
marmalade-client (new one) side by side.
Please, let me know what you think.
