remove legacy sparsecp

sparsecp gets only used in qmextract, which is part of the old backup
method (pre PVE 2.3).
Do not remove qmextract for now people could still have backups from
< PVE 2.3 around.
They could be restored manually, but we shouldn't make restoring
complicated. Thus replace sparsecp with `cp sparse=always`.
