Merge bitcoin#24336: Print enable_fuzz_binary in configure

faef344 Print enable_fuzz_binary in configure (MarcoFalke)

Pull request description:

  A *disabled* `enable_fuzz` on current master does *not* mean the the fuzz binary is not compiled. This is confusion, so fix it.

  * `enable_fuzz` toggles compilation flags for fuzzing and disables all other target. There is no need to print this in the configure result, because the compilation flags are already printed. Also, all other targets are already printed as `no`.
  * `enable_fuzz_binary` does what it says it does and is currently not printed. So print it.
