[OE-core] [PATCH] archiver.bbclass: Fix archiver interaction with kernel recipes

[Phil Reid <preid@electromag.com.au>]

Changes to the logic of is_work_shared where made in
commit: 5fbb4ca8da4f4f1ea426275c45634802dcb5a575
"archiver.bbclass: Improve work-shared checking"

The resuled in a change of the logic (simplifed here) from:
  inherits(gcc-source) or inherits(kernel) or (inherits(kernelsrc) and srcin(work-shared))
to just
  srcin(work-shared)

With INHERIT += "archiver" in the local.conf and a kernel recipe that uses
KERNEL_PACKAGE_NAME. When KERNEL_PACKAGE_NAME is defined the kernel
source is not placed into work-shared, but the archiver ends up
deleting the source folder in the work dir, and the build subsequently fails.

Restore the previous logic while also mainting the referenced commits intent
to consider all recipes that use work-shared. Logic is now
  inherits(gcc-source) or inherits(kernel) or srcin(work-shared)
