block: set S_IFBLK for block devices instead of S_IFCHR
In barebox, block devices are a special case of character devices.
Nevertheless, differentiation can be useful to allow scripts iterating
over all block devices without accounting for naming, e.g.
for dev in /dev/*; do
test -b $dev && echo $dev: blockdevice
done
Add the necessary support. This will break scripts that assume
test -c blockdevice to be true, but that's a quite improbable check.
