Only use sanitizing options when debugging

The C compiler's sanitizing options introduce code in the output
binary which is fragile and not very security conscious.  It has
become clear that sanitizing is only really meant for use while
debugging.

As a side effect, this makes compilation faster, as the Makefile, for
production builds, no longer runs the compiler repeatedly to find all
its currently supported sanitizing options.

* Makefile (DEBUG): Add "$(SANITIZE)".
  (SANITIZE): Comment out.
  (CFLAGS): Remove "$(SANITIZE)".
  (plugins.d/mandos-client): Revert back to use plain $(LINK.c), since
                             we no longer need to remove the leak
                             sanitizer by overriding CFLAGS.
