Move from local_codechecker to moodle-cs

This commit simply, performs the move by changing the
composer requirements and changing paths to point to
the new vendor directories. That's all.

TODO: Prospect about to stop using PHP_CodeSniffer as
library and just use the binaries. That should make
things easier. (see next commit)
