Makefile performs destructive system updates (editing dotfiles, installing JRE)

[iainmerrick]

The Linux installation instructions on the website (https://openapi.bow-swift.io/docs/quick-start/installation-guide/#-linux-users) ask you to sudo make linux. Mac users may be tempted to build from the Makefile as well as the Homebrew installation doesn't currently work (#41).

The linux target breaks normal conventions and does a bunch of destructive updates:

• It both builds and installs (usually make install is a separate step)
• It creates system installation directories before building, not after
• It installs system-wide openjdk-8-jre-headless
• It installs bash and zsh code completions

Installing dependencies, building the code and installing the code should be separate targets.

It should be possible to both build the code and execute it locally without using sudo.
