modify cmake to build nc

- modify structure of CMakeLists.txt under apps/
  * move apps/CMakeLists.txt to apps/openssl/ since this is for openssl build
  * create new apps/nc/CMakeLists.txt for nc build
  * modify apps/CMakeLists.txt just add_subdirectory()

- add checking and compile of arc4random_uniform()

- add installing man files, openssl.1 and nc.1
