package_manager: call createrepo with --dbpath pointing inside WORKDIR
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 during previous run of createrepo.
Made createrepo to create rpm db in $WORKDIR/rpmdb/ from scratch
for every build and architecture. This should potentially fix the
failure as every run of createrepo will be using separate db.
