vt: fix canonical input in UTF-8 mode
For e.g. proper TTY canonical support, IUTF8 termios flag has to be set as appropriate. Linux used to not care about setting that flag for VT TTYs. This patch fixes that by activating it according to the current mode of the VT, and sets the default value according to the vt.default_utf8 parameter.
