xbps-rindex: check for consistent shlibs

When adding packages to the index, xbps-rindex will check if the
consistency of shlibs is broken by a package. If so, rindex will create
a stage file and commit the packages there. Once the consistency is restored,
rindex -a will commit the stage area back to the public repo and delete the
stage file.
