File quilt-setup-05-fix-check_for_existing_files.patch of Package quilt

Fix handling of directory names including white spaces by
check_for_existing_files. awk can't deal with tokens which include
white spaces, so use bash's read function instead.

As a side bonus, we get rid of the undocumented dependency to "uniq".
