Peter Müller b7b65e736e sysctl.conf: prevent unintentional writes into attacker-controlled files and FIFOs

patch enables protections against unintentional writes into
attacker-controlled regular files or FIFOs, where a program expected to
create new ones. This makes exploiting TOCTOU flaws harder.
