Remove FLAG_STDERR_TTY.

Browse Source 
It really had no need to be a global process flag at all: it's used to
signal to uxcons.c that stderr_tty_init() ought to check whether
stderr is a tty (in order to save its termios across interactive
prompts and so forth). But the only _caller_ of stderr_tty_init is
Unix Plink, which always sets that flag! So we already have a
perfectly good system for signalling to uxcons.c that you'd like
stderr_tty_init to do something: _whether you call it or not_.
