[PATCH] sstate: Ensure populate_lic sstate objects are cleaned

[Richard Purdie <richard.purdie@linuxfoundation.org>]

do_cleansstate wasn't cleaning do_populate_lic sstate objects in the
native/cross case since the wildcard path entry wasn't being cleared
at the same time as the path extra prefix. Fix by clearing it at the
same time.
