[RFC][PATCH] packagegroup.bbclass: Drop build-time dependencies

[Martin Jansa <martin.jansa@gmail.com>]

* RFC because:
  packagegroup.bbclass inherits allarch and by default sets
  PACKAGE_ARCH = "all", but then it has runtime-dependency on
  TUNE_PKGARCH packages and different signatures, so instead
  of setting INHIBIT_DEFAULT_DEPS in addition to inherit allarch
  I would like to drop default allarch completely.
* drop virtual/kernel dependency from packagegroup-core-boot
  because kernel isn't needed to build packagegroup and building
  it doesn't influence if it's included in image or not.
