vconsole: don't do GIO_SCRNMAP / GIO_UNISCRNMAP
GIO_SCRNMAP / GIO_UNISCRNMAP are related to what setfont does with -m option - namely setting intermediate map from 8bit values into unicode values. This map is global, so single setfont invocation sets it for all applicable consoles. Furthermore calling GIO_SCRNMAP before GIO_UNISCRNMAP causes issues as the former corrupts values > 255 (UNI alone would be sufficient). The bug can be easily tested with the following conf: KEYMAP=pl FONT=LatArCyrHeb-16 FONT_MAP=8859-2
