Formalise exa-packaging script

Every time I had to build exa, I copied the files manually and checked to make sure they all had the same name. There’s now a script that does all that stuff for me, so I don’t need to remember to do it anymore.

It also does some things that weren’t being done before, including stripping the binary and listing its linked dependencies to we can tell if something like libhttp_parser has slipped in there (see #194)
