btrfs-progs: btrfstune: Rename change_header_uuid to change_buffer_header_uuid
Rename the function so its name falls in line with the rest of btrfs nomenclature. So when we change the uuid of the header it's in fact of the buffer header. Also remove the root argument since it's used solely to take a reference to fs_info which can be done via the mandatory eb argument. No functional changes.
