Revert "pid1: order units using TTYVHangup= after vconsole setup"

Browse Source 
This reverts commit e019ea738d.

In the new approach, a lock on /dev/console will be used. This lock will solve
the issue for services which run in early boot. Services which run later are
ordered after sysinit.target, so they'll run much later anyway so this
automatic dependency is not useful. Let's remove it again to make the code
simpler.
