I guess the problem is that the recipe inherits update-rc.d class and
that class wants to work with the init script. Unfortunately
uninheriting a class in a bbappend is not possible AFAIK. I am not
familiar with the details of the class whether there is a way to tell it
to do nothing.

What about 

  do_install_append() {
      (echo "#!/bin/sh" ; echo true) > ${D}${sysconfdir}/init.d/hostapd    
  }


Just guessing. Untested and I have not worked with sysv init for
years... Maybe update-rc.d requires the typcial comment section at the
beginning. If so you just add it. 

Or actually if update-rc.d refers to the comment section in the
beginning of the script you could add a patch that changes the
Default-Start: value to empty (or some runlevel you do not use).
