htop_0.7.bb: Fix htop do_configure: Ensure that ncurses is staged.

* htop's do_configure needs ncurses, but htop did only have an RDEPENDS
  on ncurses which only triggers a build of of ncurses after or in parallel
  to htop's do_configure, which is too late. Fix this:
  Since htop is dynamically linked against ncurces, OE detects the REDEPENDS
  to ncurses automatically and we can simply change the RDEPENDS to DEPENDS.
