kill: fix regression in 'kill -9'

'kill -9' was found to fail with an 'Invalid argument' error.

This is a regression introduced by commit 569de936a (kill: killing
a zombie process should fail).

Use the correct argument to OpenProcess() for SIGKILL so it can
query the exit code of the target process.

Adds 16 bytes.
