bitbake: bitbake-setup: support adding environment-passthroughs to the init-build-env

This patch adds support for extending the BB_ENV_PASSTHROUGH_ADDITIONS
environment variable from within the `init-build-env` wrapper script -
generated by either oe-core's oe-setup-build, or by `bitbake-setup` -
based on per-configuration JSON settings.

This enables CI workflows to inject environment-specific data - such
as build number, host, build type, or credentials required to fetch
from certain SRC_URIs - which cannot be captured via configuration
fragments alone. These variables are now handled early in the setup
process and exported directly into the build environment.

Example:

  "bb-env-passthrough-additions": [
      "ACME_DIR",
      "ARTIFACTORY_TOKEN",
      "ARTIFACTORY_USERNAME",
      "GITHUB_TOKEN",
      "GITHUB_PROTOCOL",
      "KEY"
  ]
  <snip>

the resulting 'init-build-env' would then be:
  # environment passthrough added by bitbake-setup
  export BB_ENV_PASSTHROUGH_ADDITIONS=" \
  $BB_ENV_PASSTHROUGH_ADDITIONS \
  ACME_DIR \
  ARTIFACTORY_TOKEN \
  ARTIFACTORY_USERNAME \
  GITHUB_TOKEN \
  GITHUB_PROTOCOL \
  KEY"
  # init-build-env wrapper created by bitbake-setup
  . /tmp/acme_master-acme-distro_acme-machine_bang/layers/openembedded-core/oe-init-build-env /tmp/bitbake-setup/gs/acme_master-acme-distro_acme-machine_bang/build
