[PATCH] Braille screen reader fixes

[Samuel Thibault <samuel.thibault@ens-lyon.org>]

Braille screen reader fixes:
- console_cmdline's brl_options field is only required when braille
console support is enabled.
- Use strlcpy to copy the console name.
- braille console support depends on VT support.
