    lib/oe/sstatesig: fix finding native siginfo files in sstate-cache
    
    When comparing signatures with bitbake-diffsigs -t or bitbake -S
    printdiff, we use this find_siginfo() function implemented in this
    module to find the siginfo/sigdata files corresponding to the tasks
    we're looking for. However, native sstate files go into a
    NATIVELSBSTRING subdirectory and there was no handling for this when
    asking about native recipes.
    
    I'm not even sure why we were walking SSTATE_DIR in order to find
    this - we don't need to, we just need to run glob.glob() on the filespec
    we calculate, which should be a little bit more efficient.
