Add option to ignore files and folders with nodump flag
Many backup tools support a special filesystem flag, that allows to mark files and folders to not be backed up. In order to estimate the backup size, it's benefical to have Filelight also ignore files and folders with the nodump flag. The nodump flag is supported on some filesystems (e.g. ext2/ext3/ext4 and btrfs). For more details see chattr(1).
This feature is only available if the statx function is provided, which means effectively (according to statx(2) manpage):
- Linux 4.11
- glibc 2.28
