NSE C modules fixed in static builds

[David Fifield <david () bamsoftware com>]

Hello,

I just made a change that fixes NSE C modules in static builds of Nmap.
libtool needs to link the modules with liblua and libm or else not all
needed functions are included. Trying to load a module (bit.so is
currently to only one) from a static build caused an error 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]: ?
        [C]: in function 'require'
        /usr/share/nmap/nselib/packet.lua:12: in main chunk
        [C]: in function 'require'
        /usr/share/nmap/scripts/rpcinfo.nse:10: in main chunk
        [C]: ?
        [C]: in function 'Entry'
        /usr/share/nmap/scripts/script.db:8: in main chunk
        [C]: ?
        [C]: ?

That this didn't work before is kind of a big deal because the binaries
shipped in the RPM packages are static. I tested RPMs back to 4.23RC1
from November 2007 and they all had the problem. It probably goes back
earlier than that, that's just where I stopped testing.
