instaweb: minimize moving parts for WEBrick

Since there are WEBrick configuration settings (including the
upcoming AccessLog support) that cannot be represented in YAML
and require Ruby anyways, the YAML config file is an unnecessary
layer of complexity.

Additionally, the shell script wrapper to start WEBrick is
unecessary since our generated Ruby script can be made
executable in the same manner with /usr/bin/env.
