Update Makefile

[JugglingSuns120]

added -lncurses to the LIBS in the makefile to include the appropriate libraries. I've received build errors when trying to install via the adsbexchange install scripts on both an Ubuntu and a Debian Linux installation. The build error is related to a missing ncurses library. This pull request resolves the missing library and allows the binaries to compile.
