[f2fs-dev] f2fs-tools: fix to do not dump inode if it has F2FS_NODUMP_FL flag

Commit Message

Quoted from manual of chattr:
"
CHATTR(1)
...

ATTRIBUTES
A file with the 'd' attribute set is not a candidate for backup when
the dump(8) program is run.
"

Once we set F2FS_NODUMP_FL flag to inode, do not allow dumping info
from it.
