Update deapexer call to explictly use blkid

To support erofs apex extract via deapexer, we need blkid to tell the filesystem type of underlying payload image. If it is ext4, debugfs_static will be used, if it is erofs, then we should use fsck.erofs. Thus we now need explicit blkid input.

Also, remove dependency on fsck.erofs for other deapexer calls. Only extract deapexer call needs blkid and fsck.erofs.
