sstate-cache-management: improve shown numbers of removed files

* deleted files were counting .siginfo and .done files, but total_files were counting only .tgz archives
  so it could show confusing output like:
  Figuring out the sstate:xxx_packagedata.tgz ... (21098 from 15162 files for packagedata suffix will be removed)
* split the counts and show both
* fix .sigdata sometimes used instead of .siginfo
* this will also show new "suffixes" which have only .siginfo files but
  no .tgz, e.g.:
  Figuring out the sstate:xxx_rm_work.tgz ... (0 from 0 .tgz files for
  rm_work suffix will be removed or 0 from 107630 when counting also
  .siginfo and .done files)
  because now we're storing siginfo files from all intermediate tasks,
  but they are not being removed by this script
