[SRU] Fix black screen on second boot due to video drivers not being ready.

[Scarlett Gately Moore]

[ Impact ]

 * Users experience black screen on second boot after fresh install due to video drivers not being ready.

 * The patch adds a needs for systemd to wait until drivers are complete before sddm login manager.

[ Test Plan ]

 * New install. Reboot 2 times, you will run into a black screen ( seems random, all video drivers affected though )

 * With the random nature of the bug it cannot be cleanly reproduced. Of 3 computers only one of mine experienced the problem.

[ Where problems could occur ]

 * systemd services boot order? possibly affect something else?

 * Tested in oracular and no issues have arised.

[ Other Info ]

 * Closes {LP #2065321)

Status changed to 'Confirmed' because the bug affects multiple users.

I looked at the source code for sddm in Oracular and discovered that this change is included in it so I'm marking the Oracular task as Fix Released.

I don't understand why a second bug was created for this SRU when using bug 2063143 (of which bug 2065321 is a duplicate) would likely have more people willing to do the verification.
