Marc Palacín 1b994f7479 fix(raspberrypi): detect Raspberry Pi hardware in check mode (#719)
- set check_mode: false on the /proc/cpuinfo and /proc/device-tree/model
  probes, since ansible.builtin.command never executes under --check and
  returns rc 0 with "Command would have run if not in check mode"
- default a missing probe rc to 1 in the raspberry_pi gate so an undefined
  result cannot be read as "this host is a Raspberry Pi"
- add a structural regression test and hook it into pre-commit

Without this, site.yml --check marked every x86_64 host as a Raspberry Pi and
applied the distro specific setup tasks, failing on Ubuntu with
"Destination /boot/firmware/cmdline.txt does not exist".

# The probes below must run in check mode as well. The command module does not
# execute under --check, it returns rc 0 with "Command would have run if not in
# check mode", which would otherwise mark every host as a Raspberry Pi and make
# check runs apply the distro specific tasks. The rc values mean: 0 matched, 1 no
# match, 2 the file is absent (no /proc/device-tree on non ARM systems).
