Change upstream URL for puppet-corosync
Change upstream URL for puppet-corosync

Current URL redirects to https://github.com/voxpupuli/puppet-corosync
which is causing issues in tarname detection as repo name changes
from puppetlab-corosync to puppet-corosync.

This patch changes url to github.com/puppet-community/puppet-corosync
which redirects to the same module but keeps the same repo name.
