Revert "link mutt against ncurses (/usr/gnu/lib)"

This reverts commit 817902fb77844475ddaeaa6589a7a7422d3b546e.

Apparently omnios ncurses doesn't work correctly? starting mutt in a
remote xterm with ssh in between just seems to suspend all output until
the ssh session is disconnected (since python-curses was linked against
ncurses this also applies to 'python -c "import curses;
curses.initscr(); curses.newwin(1,1,1,1);"')
