zfsbootmenu/etc/zbm-builder

- "Tiered" configuration simplifies management and allows more targeted
  overrides, symlinking configs in `/etc/zfsbootmenu` in the container:

  1. First tier comes from `etc/zfsbootmenu` (global defaults)

  2. Second tier comes from `etc/zbm-builder` (container defaults)

  3. Third tier comes from the build root (build specific)

  Configurations in later tiers override those with conflicting names in
  earlier tiers.

- Tiered configuration now includes mkinitcpio configuration, allowing
  containers to build mkinitcpio images

- Container configuration for mkinitcpio supports dracut-style snippets
  in `mkinitcpio.conf.d`

- The builder now looks for an `rc.d` subdirectory in the build root and
  will invoke every executable file therein before generating images to
  provide a means to "terraform" the build container

- The `zbm-builder.sh` wrapper now supports a configuration file to
  allow defaults to be specified; this requires a two-pass getopts to
  find and load the configuration file before parsing remaining options

- A new option to `zbm-builder.sh`, `-R`, will remove any existing host
  files (`hostid` and `zpool.cache`) from the build root to make sure
  they are always up to date with the host versions

- The container entrypoint now configures `generate-zbm` to write its
  output directly to the desired output directory rather than staging in
  a temporary output directory, allowing `generate-zbm` to manage
  version rollovers as it does in host installations

- Remove superfluous arguments from container entrypoint to manage
  `hostid`, `zpool.cache` and `config.yaml`; the files either exist in
  the build root or the container will use defaults

- Drop `docker-compose.yml` and now-obsolete `config.yaml.default`

- Update documentation to better reflect current build procedure
