chore(tc): add dummy entropy to speed up the Linux boot

If the kernel is post 5.19 and is configured with

Linux via the device tree. This avoids delaying the Linux boot
waiting for entropy. This is particularly noticeable when
booting android but also speeds up the generation of the ssl
certificates.
