[patch] concurrent make fix

[Michal Januszewski <michalj () gmail com>]

nmap's makefile contains a race condition which can lead to build
failures when using more than one make job (make option -jx, x > 1),
see e.g. [1].  The problem is caused by libnsock using libnbase,
without specifying an explicit dependency in the Makefile.  The
attached patch fixes this by adding the dependency.
