Log message:
fix for pygrub not accepting cursor keys, after CS#15928

CS#15928 added some NetBSD fixes for xenconsole, xenconsole is
now using init_term() on the slave side of the xenconsole<->xend
pseudo terminal.  init_term() is using tcsetattr with TCSAFLUSH,
and that did flush part of pygrub''s vt100 terminal initialization
from the pty''s buffer.  The vt100 terminal emulation is supposed
to run in "vt100 application key mode" mode while the pygrub
curses program is running, but was actually running with vt100
application key mode disable because of the missing initialization
sequence.  For that reason the cursor keys didn''t work as expected.

We''re now using TCSANOW instead of TCSAFLUSH, so that the
pty''s buffer isn''t flushed when switching to/from raw mode.

And now that the NetBSD fix from CS#15928 has added raw mode setup
for the slave side of the pty, avoid doing it a second time in
the Solaris specific code.
