[PATCH] rootfs.py: Remove rpm database from staging area

[Ed Bartosh <ed.bartosh@linux.intel.com>]

Rpm database in staging area is used only by createrepo.
createrepo fails with the error
"rpmdb: BDB0060 PANIC: fatal region error detected"
if rpm database is broken from the previous run of createrepo.

Removing the databae before running createrepo can hopefully
prevent this failure to happen.
