[php-maint] Bug#794029: php5-cli doesn't satisfy php dependency for php5 metapackage

[Nick Adams]

Package: php5
Version: 5.6.9+dfsg-0+deb8u1

The metapackage `php5` has a number of options to supply php but
php5-cli is not one of those. On a host that doesn't require a web
server, this metapackage seems to require that one be installed.

Adding php5-cli to the php5 package dependency options would fix this.
