REVISION SUMMARY
Use FreeBSDs `procctl` to disable gdb&Co from attaching to kscreenlocker and
kcheckpass.
What is not so nice is that when CMake runs we get the output:
-- The following features have been enabled:
* procctl-trace , Required for disallow ptrace on greeter and kcheckpass
process
[...]
-- The following features have been disabled:
* prctl-dumpable , Required for disallow ptrace on greeter and kcheckpass
process
This should probably be unified.
Also, as this will probably crop up all over the place, would it maybe be
sensible to define some `enableTracing()` and `disableTracing()` functions so
that this change has not have to be applied everywhere?
