As we've noticed a few times now, mingw/msys/cygwin has a fairly horrible kill implementation that annoys us here. However our workaround wasn't enough - "mingw" is also a name that is used here and "msys" can also be a substring. Also we need to silence the `kill` because it's better to not list the signals than it is to spew errors. Fixes #8915.
