postmarketos-initramfs: prevent busyloop in syslogd

Oliver Smith requested to merge ollieparanoid/pmaports:v24.12-syslogd-busyloop-backport into v24.12

Backport of !6013 (merged).

when stdin is /dev/null (e.g. when console=null is on the kernel
cmdline) syslogd will call read() over and over and never handle the
SIGTERM we send it, pinning a CPU core on every boot.

Hooking up syslogd std I/O to /dev/zero prevents this.
