[PATCH] package_manager: Run createrepo sequentially

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

Running multiple createrepo in parallel can cause raice conditions
when creating/accessing rpm database. Createrepo fails with the
error "package_manager: rpmdb: BDB0060 PANIC: fatal region error detected"
in such cases.

Running createrepo sequentially should fix the race as rpm database
will not be accessed by multiple createrepo at the same time.
