Timezone sync issue between the host and containers (sonic-net#14000)

#### Why I did it
To fix the timezone sync issue between the containers and the host. If a certain timezone has been configured on the host (SONIC) then the expectation is to reflect the same across all the containers.

This will fix [Issue:13046](sonic-net#13046).

For instance, a PST timezone has been set on the host and if the user checks the link flap logs (inside the FRR), it shows the UTC timestamp. Ideally, it should be PST.
