vgabios: Don't interpret TAB character.

Several sources document that the Bell, Backspace, newline, and
carriage return characters are interpreted by int 10/0e.  There does
not seem to be any references to that function interpreting tab.  The
original "lgpl vgabios" has code for interpreting tab, but the code is
incorrect.  Finally, tests on an ATI vgabios indicate that tab is not
interpreted.
