php: don't install phpX.X metapackage

THe phpX.X package is actually a meta-package that depends on
libapache2-mod-phpX.X | phpX.X-fpm | phpX.X-cgi. Installing the meta
package before php-fpm / nginx might causes the Apache module to be
installed which we don't want. Fix this by installing the -common and
-cli packages in the php class. The php::fpm class will still install
the -fpm package.
