Subject: [PATCH] src.opts.mk: Comment about CTF & DTRACE relationship

WITH_CTF enables building userland components with CTF, and not the ctf*
tools as one might expect.  The tools are actually included with the
DTRACE knob.  Add a comment where the dependency is handled, as this has
caused confusion.
