Subject: [PATCH] Remove missing declaration warning (#6330)

When I built Citus on PG15beta4 locally, I get a warning message.

```
utils/background_jobs.c:902:5: warning: declaration does not declare anything
      [-Wmissing-declarations]
                                __attribute__((fallthrough));
                                ^
1 warning generated.
```

This is a hint to the compiler that we are deliberately falling through
in a switch-case block.
