specs/qcow2: do not use wording 'bitmap header'
A bitmap directory entry is sometimes called a 'bitmap header'. This
patch leaves only one name - 'bitmap directory entry'. The name 'bitmap
header' creates misunderstandings with 'qcow2 header' and 'qcow2 bitmap
header extension' (which is extension of qcow2 header)
