[OE-core] [PATCH] package_manager: call createrepo with --dbpath pointing inside WORKDIR

[Ed Bartosh]

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. This should potentially fix the failure.
