archiver.bbclass: some recipes that uses the kernelsrc bbclass uses the shared source

This fix a race that happens when building some of the followning recipes
with kernel at same time.

The kernelsrc uses the kernel shared source dir as their source
S = "${STAGING_KERNEL_DIR}" and this will cause a race in the
do_unpack_and_patch task, when bitbake runs the
bb.build.exec_func('do_unpack', d) because do_unpack will
clean the source dir on startup.

| ok: note that S != "${STAGING_KERNEL_DIR} for this ones

The issue can be replicated with:

INHERIT += "archiver"
ARCHIVER_MODE[src] = "original"
ARCHIVER_MODE[diff] = "1"

And:

R=<recipe> bitbake -c cleansstate virtual/kernel $R && bitbake $R
