populate-extfs.sh: fix to handle special file names correctly
`debugfs' treats spaces and "" specially. So when we are dealing with file names, great care should be taken to make sure that `debugfs' recognizes file names correctly. The basic solution here is: 1. Use quotation marks to handle spaces correctly. 2. Replace "xxx" with ""xxx"" so that debugfs knows that the quotation marks are parts of the file name.
