Allow registering TTYs that are not yet available

Browse Source 
This patch removes the following very annoying warning for TTY devices
not yet available, i.e. plugged-in to the system.

Loading configuration ............................................................................. [ OK ]
[   11.097414] finit[1]:tty_register():Incomplete or non-existing TTY device given, cannot register.
[   11.101457] finit[1]:tty_register():Incomplete or non-existing TTY device given, cannot register.
Mounting filesystems .............................................................................. [ OK ]

Finit will not start a getty (built-in or external) if the TTY does not
exist, but having the configuration enabled makes it possible to do a
simple `initctl reload` to activate a plugged in TTY.
