[BRLTTY] Starting brltty as early as possible.

Hi,

This is simply great.

I would keep the code, with the possibility to activate it through an
option on the cccommand-line or somewhere in brltty's configuration
file. The ability of brltty to set the system up as needed is precious,
I believe, in contexts like distribution installation, creation of boot
CDs, etc.

Cheers,
Sébastien.
