[PATCH 1/3] test: py: linux: use utilities available in Debian netinstall images

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

The Debian CDROMs for netinstall on ARM64 don't have journalctl (no
systemd) and no stat or strings.

Adapt the tests we have to use the commands available within the busybox
included on the CDROM images.
