test: ignore LXC filesystem when checking for writable locations

test-execute checks that only /var/lib/private/waldo is writable, but there are
some filesystems that are always writable and excluded. Add /sys/devices/system/cpu
which is created by lxcfs.

Fixes https://github.com/systemd/systemd/issues/23263
