Enhance the error message output mechanism (#14384)

#### Why I did it

Enhance the error message output mechanism during swss docker creating

#### How I did it

Capture the output to stderr of `sonic-cfggen` and output it using `echo` to make sure the error message will be logged in syslog.

#### How to verify it

Manually test
