hdparm: replace stat with coreutils as runtime dependency
Currently only hdparm specifies stat as runtime dependency in oe-core.
But the stat hasn't any update since 2002. Replace it with coreutils as
runtime dependency since coreutils also provides stat program. Then we
can drop the stat recipe totally.
Also add a patch to fix stat path in wiper.sh.
