Overhaul Makefile.in and configure.ac to link NSE C modules explicitly with

liblua and libm. This is necessary for static builds of Nmap, such as RPM builds. Before this the error that was caused looked like SCRIPT ENGINE: error while initializing script rules: error loading module 'bit' from file '/usr/libexec/nmap/nselib-bin/bit.so': /usr/libexec/nmap/nselib-bin/bit.so: undefined symbol: lua_pushnumber stack traceback: [C]: ?
