Don't undef <unit>_TRACE, instead add comment how to enable it

In units that support detailed reference tracing via ISC_REFCOUNT
macros, we were doing:

    /* Define to 1 for detailed reference tracing */
    #undef <unit>_TRACE

This would prevent using -D<unit>_TRACE=1 in the CFLAGS.

Convert the above mentioned snippet with just a comment how to enable
the detailed reference tracing:

    /* Add -D<unit>_TRACE=1 to CFLAGS for detailed reference tracing */
