windows: make zsyscall_windows.go generatable on non-WSL env

mkerrors.bash requires a Windows host, as it hard-codes paths like
/mnt/c/Program Files (x86)/Windows Kits.
But this does not allow to generate in non-WSL env.

Currently mkerrors.bash runs earlier than mksyscall_windows.go
when we run `go generate` and it fails on non-WSL env.
So zsyscall_windows.go is not generated in that case.

To fix that, I reoreder of code generation in this CL so that we can
generate zsyscall_windows.go in non-WSL env.

Also update error message in mkerrors.bash.
