[PATCH 1/2] cachability: ignore BBLAYERS in get_build_id

[Felix Moessbauer <felix.moessbauer@siemens.com>]

The get_build_id task just provides a convenience check for
issues around a missed ISAR_RELEASE_CMD.
While it uses the BBLAYERS variable internally, this does not
have any effect on a generated artifact, hence the value of the
variable can be ignored.
