Subject: [PATCH] v2v: linux: do not uninstall open-vm-tools w/ ubuntu-server

ubuntu-server depends on open-vm-tools on Ubuntu, so if v2v tries to
uninstall open-vm-tools then dpkg will (rightfully) fail with a
dependency issue.

Since open-vm-tools is harmless after the conversion anyway (it will
not even run), then do not attempt to uninstall it if ubuntu-server is
installed too.

Followup of commit 2bebacf8bf611f0f80a66915f78653ce30b38129.

Thanks to: Ming Xie.

(cherry picked from commit 1a4fd822ef057764f809cddce642b3223756629e)
