autoconf: add check for curses library

Check for a curses compatible library (curses or ncurses basically).
One of those is needed to compile Xen tools (gtraceview and xentop).

Modify Makefiles/sources to use configure output (fetch CURSES_LIBS
from tools/Tools.mk and header to include from tools/config.h)
