MT#60283 Update grml-live to version 0.54.1

Lots of changes took place in between v0.53.2 and v0.54.1. To ensure to
follow upstream changes, let's make sure our configuration avoids
relying on features that are going to be dropped in upcoming versions.

Relevant changes:

* FAI_DEBOOTSTRAP=... became BOOTSTRAP_MIRROR=... (without the Debian
  release name, but just requiring the mirror URL)

* the templates command line option `-t ...` is considered deprecated,
  now that boot templates are also class-based configuration files
  (via ${GRML_FAI_CONFIG}/config/media-files/$CLASS)

  Let's keep our templates as-is, but provide
  grml_build/config/media-files/SIPWISE as symlink to our templates
  directory

* GRMLBASE and architecture-specific classes are now enabled by
  default and no longer should be included in the grml-live invocation,
  so drop GRMLBASE + AMD64 class names in wrapper.sh

* The RELEASE class (which cleans up /root and /home/grml) is also
  automatically enabled, but since we e.g. ship files like /root/puppet.gpg
  we need to disable this new behavior by enabling the new "-R" option
