amdadl-sdk: set license to unfree (close #1647)

We cannot auto build amdadl-sdk on hydra, so setting license to unfree disable

vcunat changed string license to attribute.
fixup previous commit: do the change to attribute
httpd: Only add PHPRC to environment of httpd when enablePHP is true.
httpd: Respect original order of environment eval.
