php.buildEnv: Make the exported php package overridable

Browse source 
This implements the override pattern for builds done with buildEnv, so
that we can, for example, write

php.override { fpmSupport = false; }

and get a PHP package with the default extensions enabled, but PHP
compiled without fpm support.
