tdf#144996 XLSX export: keep permission for editing on save

The password for editing lost on Save, breaking the workflow
with newer MSO versions, i.e. after saving, it was possible
to modify the file on its original path without password.

Manual test:

- Open an XLSX document with permission for
editing e.g. created with Excel 2019 or newer;

- Choose Edit->Edit Mode and give the permission for edit
  with the requested password;

- modify the file, and save it with File->Save. The file
  workbook.xml keeps <fileSharing> with the original hashValue,
  saltValue and spinCount.
