Add dynbinary and dyntest scripts for building/testing a separate static dockerinit binary

Browse Source 
After a nice long brainstorming session with @shykes on IRC, we decided on using a SHA1 hash of dockerinit compiled into the dynamic docker binary to ensure that we always use the two in a perfect pair, and never mix and match.
