Why I did it

This fix resolves issue with missing certain types of messages while forwarding to the remote server.

Basically, this moves remote syslog forwarding rules to be executed before any other instructions take place,
so everything received by a local syslog instance will be forwarded to the remote machine.

The fix allows remote forwarding of messages defined as:
https://github.com/sonic-net/sonic-buildimage/blob/master/files/image_config/rsyslog/rsyslog.d/00-sonic.conf.j2

#### How to verify it
<!--
If PR needs to be backported, then the PR must be tested against the base branch and the earliest backport release branch and provide tested image version on these two branches. For example, if the PR is requested for master, 202211 and 202012, then the requester needs to provide test results on master and 202012.
-->
1. Enable remote syslog forwarding
2. Check for message patterns defined as [00-sonic.conf.j2](https://github.com/sonic-net/sonic-buildimage/blob/master/files/image_config/rsyslog/rsyslog.d/00-sonic.conf.j2)
