Revert "Add test case for rhbz#742885"

The test case is wrong - it's testing for whether tboot is used without
configuring tboot to be used.  To do this right requires setting
HYPVERVISOR= before running the test.

So for now revert, until I have a chance to do it right.

This reverts commit 4a9008b640bbe8833ac9864b795d98d7adb52914.

Fix empty root device in case of an empty /etc/fstab

In this case we have the only option - to check for /proc/cmdline
which must contain a valid root device description.
