meta-html5-framework/wam: adjust how wam is started

WebAppMgr has to be launched for each user (but not through
the systemd user session as it would require too much privileges for the user).

For this purpose, we create a systemd service instanciated for each user
by the application framework through afm-user-session@ service.

This patch also distributes the environment and service file near the recipe
instead of having those integration files in the sources (it's easier to follow
AGL evolution without changing the upstream source code)

Also, for the HTML5 demos to work, each app must request the following permissions in
their config.xml:
	<param name="urn:AGL:permission::public:display" value="required" />
	<param name="urn:AGL:permission::public:audio" value="required" />
