a small fix for QNX 6.x

[Dmitry Alexeyev <dmi_a qnx org ru>]

Hello.

QNX 6.x console driver (both devc-con and devc-pcon) is a bit buggy
dealing with 8bit characters. A.e. printing out 0x9a leads to
inserting a weird string ' 6c' to stdin.
One can't use full 8bit output with mc, cause localized filenames or
viewing binary file could corrupt the screen or even crash mc itself.

There's a small hack against it:
