uml: handle errors on opening host side of consoles
If the host side of a console can't be opened, this will now produce visible
error messages.
enable_chan now returns a status and this is passed up to con_open and
ssl_open, which will complain if anything went wrong.
The default host device for the serial line driver is now a pts device rather
than a pty device since lots of hosts have LEGACY_PTYS disabled. This had
always been failing on such hosts, but silently.
