winedos fix: get device data

[Rein Klazes]

Hi,

This fixes LHA.EXE (archiver for LZH files), used by an installer of an
old windows program, SeedMaster.

Changelog:

	dlls/winedos	: int21.c
	In int21_ioctl - get device data-, set the "is console" bits if
	the device handle is a tty or a proper console io handle.

Rein.
