- Fix logic error in scripts to build kernel modules locally - see bnc#1042726.
Fix "requires" for net-tools-deprecated so that Leap 42.3 will build.
Fix missing /media for Leap 42.3.
Fix typo in above changes.

- Fix some typos in the various service files as noted in boo#1044931.
With these fixes, TW guests start correctly. In addition, the /sbin/vboxconfig (for hosts) and the
/sbin/vboxguestconfig (for guests) work correctly.

- Now that kernel:HEAD:standard has changed to version 4.12.0-rcX, the VB drivers need some changes for new API's.
File "vbox_fix_for_kernel_4.12.patch" is added.
The added installation of "net-tools-deprecated" broke builds for Leap 42.3. That change is now conditional on building for Factory.

- Add installation of package "net-tools-deprecated" as requested in boo#1027742.

- Revise warning screen concerning USB passthru - fixes bnc#1041137.
USB passthru opens a security hole, yet it is so valuable that many users want the feature, thus it is our default.
Previously, a user needed to edit a udev rule to disable passthru. The bad part was that an update of VB changed the
rule back to allow passthru without any notification. These changes modify the popup to allow the user to accept or decline
passthru. If the user declines, then the root password is requested and the udev rule is modified. As these modifications will be
lost with the next VB update, the inode of the udev rule is kept. If the user has previously declined and the inode has changed,
the popup will show the next time VB is started. File "fix_usb_rules.sh" is added.
