#23 Link libcunit against curses lib when curses is enabled

[Joshua Root]

When curses is enabled, libcunit uses some curses symbols and thus needs to be linked with the curses lib. This unfortunately isn’t caught at build time because libtool is for some reason telling the linker to allow undefined symbols. (Not doing that would be a good idea too, but I couldn’t figure out what to change.)
