Subject: [PATCH] arg: Flush log before exiting after usage() (#25504)

Under certain conditions, it's possible for messages emitted via LOG()
to get lost before exit, apparently because they are emitted by another
thread. common_params_print_usage() uses printf directly, and is not
affected.

Flushing the log before exit seems to resolve this.
