The sysctl(8) program exits on some errors and only emits warnings on

others. In the case where it displayed warnings it would still return
succesfully. Modify it so that it returns the number of sysctls that
it was not able to set.

Make use of this in rc.d to display only *unsuccessfull* attempts to
set sysctls.
