cleanup and bashify install hooks

No logical code changes -- this is purely a syntactical cleanup and
standardization across the build hooks along with ensuring that help
messages are wrapped to 80 columns or less. All hooks get the same
treatment, adhering to the following style:

  #!/bin/bash

  build() {
      COMMANDS
  }

  help() {
      cat <<HELPEOF
  This is a help message.
  HELPEOF
  }

  # vim: set ft=sh ts=4 sw=4 et:
