Move the web-service apps to python3-gfhardware/forgefirm-app

gfhome.py, ffmachine.py, and gfcloud.py (with the gfcloud init script
and gfhome conf sample) live in the python3-gfhardware repository's
forgefirm-app/ directory. The three recipes fetch that repo through a
shared include (forgefirm-app.inc) carrying a single pinned SRCREV,
replacing the local file:// copies. Package names, dependencies, and
installed paths are unchanged.
