- Fix crash with ncurses on FreeBSD/amd64 CURRENT by including missing

header <term.h>, which is required by both tputs() and tgoto().

  Without this header, nvi crashes with the call to tputs() at line 114.
  This is because the first argument of tputs() is a pointer, and the
  returned pointer from tgoto() is casted to an integer by compiler.

  For some reasons, this only crashes on amd64+CURRENT. On 6.x system,
  this does not happen.
