Transfer ownership to emacs-php

[stevenremot]

Following emacs-php/php-mode#235, the ownership of this package will be transfered to the @emacs-php group.

Tasks to perform:

• Move the repository
• Update the MELPA recipe
• Ensure the CI works properly
• Update references to the old repository URL to the new one

I would like to know if you see other tasks to do @zonuexe , either for ownership transferring, or for making it easy for others to contribute.

PR done on MELPA: melpa/melpa#5716

The CI build is totally broken, I think I will have to update the way emacs is installed.
