btrfs-progs: mkfs: print type of subvolume in the listing

Browse Source 
Print indicators in the summary if the subvolume is read-write,
read-only or default:

$ mkfs.btrfs --subvol ro:subvolro --subvol rw:subvolrw --subvol default-ro:defaultro --rootdir /rootdir/path img
...
Rootdir from:       /rootdir/path
  Compress:         no
  Subvolume (rw):   subvolrw
  Subvolume (ro):   subvolro
  Subvolume (dro):  defaultro
...

The path is relative to the rootdir path and may not be a subvolume in
the source directory so drop the rootdir as this may be confusing.
