[OE-core] [PATCH] sstate: Add handling of do_shared_workdir task

[Richard Purdie]

Changing TMPDIR and rebuilding an image was resulting in rebuilds of
kernels due to dependencies on the shared_workdir task. If installed
from sstate, nothing needs this task so add it to the whitelisted
task patterns.

After this change, the kernel does not rebuild when a new TMPDIR and
hot sstate cache is used.
