Revert "Remove procps support for now."

This reverts commit 46f99c303712d799a3d18f444b31100847f20053.

Bug #734610 has been fixed. Closes: #734547, #735375
open-vm-tools.init: add status
list useful modules in open-vm-tools-dkms

According to
http://sourceforge.net/p/open-vm-tools/mailman/message/30762051/
http://sourceforge.net/p/open-vm-tools/mailman/message/30282524/
the modules vmci, vsock, vmblock and vmsync are not required for kernels >3.9.

Since vmxnet3 is included in the kernel, the only useful module in this package
is vmhgfs for shared folders support.

Closes: #724574
