In Meadow OS, if included in build, diagnostic code outputs PID of new threads. Can this be simplify?

Describe the bug
The original request

The PID output code which we repeat over and over. I’d like us to look at doing something about the fact that we repeat the same three lines.

For reference the "same three lines" are in Meadow OS 28 times and look like one of the following:

#if HCOM_DIAG_OUTPUT_SYSLOG_PID_OF_NEW_THREADS > 0
    syslog(2, "New pthread [PID:%d],'%s'\n", getpid(), "hcom_mono_control");
#endif

#if HCOM_DIAG_OUTPUT_SYSLOG_PID_OF_NEW_THREADS > 0
  syslog(2, "New kthread [PID:%d],'%s'\n", getpid(), MEADOW_TIMER_EXPERIMENT_THREAD_NAME);
#endif

Please note that the code is only included in the build if in
/nuttx/include/meadow/hcom_shared_common.h the following is set to '1'
#define HCOM_DIAG_OUTPUT_SYSLOG_PID_OF_NEW_THREADS 0
