misc/far2l: try to further improve information panel displayHEADmain

- Follow existing logic for volume name and do not show empty
  disk serial number
- Obtain volume name by invoking fstyp(8) utility as it seems
  we currently do not have a library function for that
- In the InfoList::PrintInfo() method, call CellsCount()
  instead of GetLength() to handle strings with double-width,
  e.g. CJK characters correctly
