Pass LUKS password as needed when resizing open mapping (#59) 

This is the final piece which enables GParted to pass the LUKS
passphrase when resizing an open LUKS encryption mapping when
'cryptsetup resize' will prompt for it.

Closes #59 - Resize of LUKS2 encrypted file system fails with "Nothing
             to read on input"
