More fixes for the Windows GN build.

- symupload.exe is the same binary, but with the LargeAddressAware bit set (https://msdn.microsoft.com/en-us/library/wz223b1z.aspx)
- mini_installer_version.rc should be mini_installer_exe_version.rc and should be placed in the out directory (according to the GYP files).
- Cleaned up the courgette64 copy rule.
