bitbake: tinfoil: fix config_data mess up insane check while parsing multiple recipes

Since commit [tinfoil: Simplify remote datastore connections][1] and
[tinfoil: Add back ability to parse on top of a datastore][2] applied,
bitbake run command parseRecipeFile with param config_data.dsindex rather
than config_data.

While calling tinfoil.parse_recipe_file() with one config_data (with the same
config_data.dsindex) to parse multiple recipes, it will mess up insane check.

It broke update_layer.py on layerindex, here are the simplified steps:
[snip]
t= bb.tinfoil.Tinfoil()
t.prepare()
data = bb.data.createCopy(t.config_data)
fn = "path_to/oe-core/meta/recipes-graphics/images/core-image-clutter.bb"
t.parse_recipe_file(fn, appends=False, config_data=data)
fn = "path_to/oe-core/meta/recipes-graphics/packagegroups/packagegroup-core-x11-base.bb"
t.parse_recipe_file(fn, appends=False, config_data=data)

|  File "path_to/oe-core/meta/classes/insane.bbclass", line 1303,
in __anon_1304__path_to_oe_core_meta_classes_insane_bbclass
|    bb.fatal("Fatal QA errors found, failing task.")
[snip]

In above failure, RDEPENDS is assigned `${PACKAGE_INSTALL} ${LINGUAS_INSTALL}
${IMAGE_INSTALL_DEBUGFS}' in core-image-clutter.bb, but it broke insane check
on packagegroup-core-x11-base.bb

>From commit [remotedata: enable transporting datastore from the client to
the server][3], it create a new DataSmart to save receive_datastore's remote_data
Similarly, make a copy of config_data(with different config_data.dsindex) could
fix the issue.
