Working 9.4.6 build

* Update version to 9.4.6 with relevant patches.
* Rename dkms.conf to dkms.conf.in to follow practices of other packages.
* Add open-vm-tools-dkms.install file for automatic installation/removal
  of the dkms modules when the package is (un)installed.
* Change package numbering to reflect the Arch standards.
* Delete dkms sources that aren't needed from the package:
  vmblock is now provided via the FUSE module for kernels >= 3.0. vmci
  and vmsock have been merged into kernels >= 3.9. vmsync is not needed
  since kernels >= 3.0 support FIFREEZE/FITHAW ioctls.
