Tobias Klauser d74bf73be0 os: use wait6 to avoid wait/kill race on netbsd
Resend of CL 315281 which was partially reverted by CL 354249 after the
original CL was suspected to cause test failures as reported in #48789.
It seems that both wait4 and wait6 lead to that particular deadlock, so
let's use wait6. That way we at least don't hit #13987 on netbsd.

Updates #13987
For #48789
For #50138
