console: add question-mark escape operator

Some termcaps (found using SLES11SP1) use [? sequences. According to man console_codes (http://linux.die.net/man/4/console_codes) the question mark is a nop and should simply be ignored. This patch does exactly that, rendering screen output readable when outputting guest serial consoles to the graphical console emulator. Signed-off-by: Alexander Graf <agraf@suse.de>
