Fix error with being unable to install php codesniffer on ubuntu 12.10

Recipe for PHP Codesniffer was specifying php_pear instead of
the internal chef_php_extra_pear, which was resulting in the following
error:

Added php-intl
Update metadata.rb
Update module_memcache.rb
Fixed predis recipe dependency to work for all PHP versions/platforms.

The dependency on 'php5-dev' was hard-coded into the predis recipe, but that doesn't work in all cases (I'm using PHP 5.3 IUS on CentOS 6.4 for example). The module_dev recipe already determines the right package for each platform, so it can use that instead.
