meta-app-framework: applaunchd: run under a separate user
Since applaunchd needs to start/stop systemd units, the user is granted
elevated systemd unit-management permissions via PolKit policy. If applaunchd
and all the apps run under the same agl-driver user, all the apps have these
elevated systemd permissions too. Separating them into different users allows
removing elevated systemd unit-management permission from individual apps, but
leaving such permission for applaunchd, which enhances overall security of
the system.
- add new applaunchd user and group
- switch applaunchd (gRPC) service to be started under new user
- since HTML5 apps haven't migrated to gRPC yet and still use D-Bus API,
applaunchd-dbus gets activated by agl-session and runs under agl-driver
- temporarily add agl-driver user into the applaunchd group and switch
PolKit policy to check for applaunchd group, instead of the user
- once D-Bus API is completely deprecated, agl-driver user can be removed
from applaunchd group
