Add script to review package PRs
This script will take a series of packages and build them in a COPR
(creating the repo if it doesn't exist). This acts as a basic sanity
check for updating a package: if it and the specified dependencies build
in a Rawhide COPR, it is likely safe to push this out to all of Rawhide.
Note that this generates a SRPM locally; in that sense, it should be
relatively safe to run, but the remote PR must be inspected prior to
execution of this script.
