Fixes#4582

Produces zig target output like:
"triple": "x86_64-freebsd.13.0.95...13.0.95-gnu",

Catch unreachable because:
error.PermissionDenied: Only happens when setting values
error.SystemResources: Memory is already allocated on the stack
error.NameTooLong: Known good value
error.UnknownName: Known good value
error.Unexpected: The pointers are to stack values (EFAULT), and the sysctl name is known good (ENOTDIR, EISDIR)

Catch unreachable because:

I appreciate the explanation of each reason the error is not possible - can you move this valuable information into the code?

catch|err|switch (err) {
error.PermissionDenied=>unreachable, // Only happens when setting values...
}

What's really nice about this is that if a line does happen to get reached, the stack trace will show what happened along with the comment explaining why it wasn't supposed to happen!

This will also cause the compiler to detect if that function ever gained or lost error set values.
