leaseweb tier1 mirrors antergos rsync module missing

[ZNikke]

The leaseweb tier1 mirrors (ie. rsync://mirror.nl.leaseweb.net/antergos/ etc) doesn't seem to carry the antergos RSYNC module anymore, we haven't been able to sync since 2019-03-28.

Due to this we're changing ftp.acc.umu.se #177 to update from rsync://rsync.mirrorservice.org/repo.antergos.com/ instead.

I would strongly recommend to designate some more tier1 mirrors, PM me if you want ftp.acc.umu.se to sync from repo.antergos.com and provide this.
