[PATCH 4/5] meta/bitbake.conf: Use custom disk usage command for buildstats

[Uladzimir Bely <ubely@ilbers.de>]

In Isar, default "du -sh" disk usage command produces multiple
"Permission denied" warnings. Contrary to OE, Isar uses "sudo"
for rootfs creation and some path may be not available.

Also, some subpaths of rootfs may be mounted during statistics
collecting, so we have to limit "du" by one filesystem.
