sysutils/open-vm-tools: Update to 12.4.0

open-vm-tools now supports NetBSD/aarch64. At least vmhgfs-fuse has been
confirmed to be working on this platform. vmware-user is still useless
though, because it requires either Wayland running on top of recent DRM/KMS
supporting SVGA v3 (which hasn't been ported to NetBSD as of writing) or
xf86-video-vmware, which only supports SVGA v1 and v2. VMware only provides
SVGA v3 interface on AArch64 platforms so nothing can interact with VMware
graphics aside from the standard framebuffer (via xf86-video-wsfb) at the
moment.
