Debian DEBs build script

Summary:
This scripts uses fpm to build a somewhat reproducible set of debs which can be deployed to Ubuntu 14.04 hosts. The main library package carries the Folly major version number, allowing multiple versions to be installed alongside. The -dev deb is simply called libfolly-dev and will be upgraded as Folly moves forward. In accordance to the Debian packaging policies the shared libraries have their (debug) symbols stripped and saved to external symbol files, contained in the -dev deb.

sgolemon, yfeldblum you guys are my best guess to review this. Feel free to suggest additional folks if needed.
