sstatesig: skip the rm_work task signature

We can skip the rm_work task signature to avoid running the task
when we remove some tasks from the dependencie chain.

The inject_rm_work handler on the rm_work bbclass triggers the
rm_work task running for any signature change in the dependencie
chain of the task do_build of each recipe.

i.e INHERIT:remove = "create-spdx" will trigger the do_rm_work
when we collect the sstate cache with INHERIT = "create-spdx"
