[Trixie] Add hwclock binary

[vivekrnv]

Why I did it

hwclock is not installed by default on trixie

And we are seeing following errors in chrony service

sonic INFO systemd[1]: Starting chrony.service - chrony, an NTP client/server...
sonic INFO chrony-config.sh[1148150]: hwclock --show failed, attempting hwclock --systohc...
sonic INFO chrony-config.sh[1148212]: /usr/bin/chrony-config.sh: line 6: hwclock: command not found
