btrfs-progs: list-chunks: update column names

Make the column names more descriptive, PNumber is from times when there
was only physical sort. Make the type/profile more explicit, later it
can be filtered by that. The 'Age' reflects the current allocation
strategy to always pick a higher number but this could become confusing,
it's really the number when sorted by logical offset.
